Bruh is not a word. It is a sound. It is exhaled, not spoken. It means disbelief, annoyance, or resignation. "Bruh, you ate my leftovers." "Bruh, I failed the test." "Bruh." The tone is flat. The vowel is long. It is a reaction to something stupid, unfair, or absurd. It is the verbal equivalent of a slow blink.

The word is a variant of "bro." It spread through memes and Vine videos in the mid-2010s. A clip of a man saying "bruh" in a crowded room became a template. Now it is everywhere. It is used by teenagers, gamers, and office workers. It is not formal. It is not aggressive. It is a shared sigh.

How to use it

• Disbelief: "Bruh, did you see that?"
• Annoyance: "Bruh, come on."
• Resignation: "Bruh." (alone, with a shrug)
• Greeting: "Bruh." (with a nod)

Bruh is flexible. It can start a sentence, end one, or stand alone. It can be typed in all caps for emphasis. It can be whispered. It is a pause, a reaction, a mood. It does not solve problems. It acknowledges them. Sometimes that is enough.
