When your friend/someone does something stupid.
Your friend: I got back with my ex
You: bruhhh
Someone who is retarded would say this to his friends ( People that don't actually think of him as their friend.)
John: bruhhh can you pass me a paper napkin
Jack: No, I'm not even your friend.
I way to express confusion from what someone said or to calmly express anger
Bruhhh is what you say when someone dose something that triggers you but not enough to make you rage or rage quit in a video game
Dude youth didn’t get the last kill bruhhh
