___ Is Crazy / That's Crazy

Definition:

Indicates something is wild or unbelievable, but often delivered as a sarcastic or disengaged response (even a space-filler) when someone isn’t really listening or doesn’t care

Context:

The phrase evolved from its original meaning of genuine shock / amazement into a versatile catch-all reaction that can range from sincere surprise to ironic detachment. "X is crazy" typically maintains more sincerity in describing something as extreme or absurd, but it can also be used to mock something mundane (reflecting Gen-Z's tendency toward exaggerated language).

"That's crazy" has become particularly notorious as the perfect filler response when someone hasn't been paying attention, essentially functioning as a polite but hollow acknowledgement. The dismissive usage gained traction through internet memes like "That's crazy, but I don't remember asking," which explicitly (and usually humorously) weaponized the phrase as a way to shut down unwanted stories.
