The most extreme of insults, so extreme they were only ever used by one man, logan paul. This insult is so devastating its power can rival that of the word nigger
When confronted with something totally awesome, a Woah-Bro will exclaim, "Woaaaaaaahhhhh brooooo".
This is the male equivalent of the "Woo-Girl".
A Woah-Bro may also be a "Dude-Bra" depending on his level of douchebaggery.
Dude 1: Did you see that girl's booty?
Dude 2: Woaaaaaaahhhhh brooooo!
Dude 1: I picked up this sick bro-tank today, take a look.
Dude 2: Woaaaaaaahhhhh brooooo!
An onomatopoeia of the sound that young children make when they cry. Of course, the number of "a"s range, from 2 to infinity. Why this habit of "waaaaaaaa"ing fades over time is because as we mature, us humans understand that crying loudly in public is embarrassing, and thus we avoid doing so.
