Last week, the phrase “You can’t lick a badger twice” unexpectedly went viral on social media. The nonsense sentence—which was likely never uttered by a human before last week—had become the poster child for the newly discovered way Google search’s AI Overviews makes up plausible-sounding explanations for made-up idioms (though the concept seems to predate that specific viral post by at least a few days).

Google users quickly discovered that typing any concocted phrase into the search bar with the word “meaning” attached at the end would generate an AI Overview with a purported explanation of its idiomatic meaning. Even the most nonsensical attempts at new proverbs resulted in a confident explanation from Google’s AI Overview, created right there on the spot.

In the wake of the “lick a badger” post, countless users flocked to social media to share Google’s AI interpretations of their own made-up idioms, often expressing horror or disbelief at Google’s take on their nonsense. Those posts often highlight the overconfident way the AI Overview frames its idiomatic explanations and occasional problems with the model confabulating sources that don’t exist.

But after reading through dozens of publicly shared examples of Google’s explanations for fake idioms—and generating a few of my own—I’ve come away somewhat impressed with the model’s almost poetic attempts to glean meaning from gibberish and make sense out of the senseless.

Talk to me like a child

Let’s try a thought experiment: Say a child asked you what the phrase “you can’t lick a badger twice” means. You’d probably say you’ve never heard that particular phrase or ask the child where they heard it. You might say that you’re not familiar with that phrase or that it doesn’t really make sense without more context.

Someone on Threads noticed you can type any random sentence into Google, then add “meaning” afterwards, and you’ll get an AI explanation of a famous idiom or phrase you just made up. Here is mine

But let’s say the child persisted and really wanted an explanation for what the phrase means. So you’d do your best to generate a plausible-sounding answer. You’d search your memory for possible connotations for the word “lick” and/or symbolic meaning for the noble badger to force the idiom into some semblance of sense. You’d reach back to other similar idioms you know to try to fit this new, unfamiliar phrase into a wider pattern (anyone who has played the excellent board game Wise and Otherwise might be familiar with the process).

Google’s AI Overview doesn’t go through exactly that kind of human thought process when faced with a similar question about the same saying. But in its own way, the large language model also does its best to generate a plausible-sounding response to an unreasonable request.

As seen in Greg Jenner’s viral Bluesky post, Google’s AI Overview suggests that “you can’t lick a badger twice” means that “you can’t trick or deceive someone a second time after they’ve been tricked once. It’s a warning that if someone has already been deceived, they are unlikely to fall for the same trick again.” As an attempt to derive meaning from a meaningless phrase —which was, after all, the user’s request—that’s not half bad. Faced with a phrase that has no inherent meaning, the AI Overview still makes a good-faith effort to answer the user’s request and draw some plausible explanation out of troll-worthy nonsense.

Contrary to the computer science truism of “garbage in, garbage out, Google here is taking in some garbage and spitting out… well, a workable interpretation of garbage, at the very least.

Google’s AI Overview even goes into more detail explaining its thought process. “Lick” here means to “trick or deceive” someone, it says, a bit of a stretch from the dictionary definition of lick as “comprehensively defeat,” but probably close enough for an idiom (and a plausible iteration of the idiom, “Fool me once shame on you, fool me twice, shame on me…”). Google also explains that the badger part of the phrase “likely originates from the historical sport of badger baiting,” a practice I was sure Google was hallucinating until I looked it up and found it was real.

I found plenty of other examples where Google’s AI derived more meaning than the original requester’s gibberish probably deserved. Google interprets the phrase “dream makes the steam” as an almost poetic statement about imagination powering innovation. The line “you can’t humble a tortoise” similarly gets interpreted as a statement about the difficulty of intimidating “someone with a strong, steady, unwavering character (like a tortoise).”

Google also often finds connections that the original nonsense idiom creators likely didn’t intend. For instance, Google could link the made-up idiom “A deft cat always rings the bell” to the real concept of belling the cat. And in attempting to interpret the nonsense phrase “two cats are better than grapes,” the AI Overview correctly notes that grapes can be potentially toxic to cats.

Brimming with confidence

Even when Google’s AI Overview works hard to make the best of a bad prompt, I can still understand why the responses rub a lot of users the wrong way. A lot of the problem, I think, has to do with the LLM’s unearned confident tone, which pretends that any made-up idiom is a common saying with a well-established and authoritative meaning.

Rather than framing its responses as a “best guess” at an unknown phrase (as a human might when responding to a child in the example above), Google generally provides the user with a single, authoritative explanation for what an idiom means, full stop. Even with the occasional use of couching words such as “likely,” “probably,” or “suggests,” the AI Overview comes off as unnervingly sure of the accepted meaning for some nonsense the user made up five seconds ago.

I was able to find one exception to this in my testing. When I asked Google the meaning of “when you see a tortoise, spin in a circle,” Google reasonably told me that the phrase “doesn’t have a widely recognized, specific meaning” and that it’s “not a standard expression with a clear, universal meaning.” With that context, Google then offered suggestions for what the phrase “seems to” mean and mentioned Japanese nursery rhymes that it “may be connected” to, before concluding that it is “open to interpretation.”

Those qualifiers go a long way toward properly contextualizing the guesswork Google’s AI Overview is actually conducting here. And if Google provided that kind of context in every AI summary explanation of a made-up phrase, I don’t think users would be quite as upset.

Unfortunately, LLMs like this have trouble knowing what they don’t know, meaning moments of self-doubt like the turtle interpretation here tend to be few and far between. It’s not like Google’s language model has some master list of idioms in its neural network that it can consult to determine what is and isn’t a “standard expression” that it can be confident about. Usually, it’s just projecting a self-assured tone while struggling to force the user’s gibberish into meaning.
