What it means
Bruh is that one-syllable sigh you drop when something's so dumb, annoying, or painfully disappointing that a whole sentence feels like wasted breath. It's half reaction, half verbal facepalm.
Usage examples
"Bruh, you locked the keys in the car again?"
"They cancelled five minutes before. Bruh."
"Bruh, you really sent the email without the attachment."
"He said he'd be there at 8 and rolled in at 10. Bruh."
Where it comes from
Bruh grew out of African American Vernacular English as a variant of bro and spread online and in spoken slang until it became its own reaction word. Instead of meaning a friend, it started doing the heavy lifting for disbelief, disappointment, or fed-up deadpan.
