no bueno

Faux Spanish disapproval

No bueno is mock-Spanish for "not good," used to signal that something is wrong, unacceptable, or a bad idea: Driving on that flat tire? No bueno.

The phrase is casual and often humorous, acknowledging its grammatical incorrectness in actual Spanish (which would be "no es bueno").

It functions as a quick verdict or warning.
