A huge bro party/beerfest in which tons of girls get "ridden".
King bros often show up to brodeos
Brodeos can involve hundreds of gallons of
beer and involve massive beer pong sessions
It is
said that to not play Dave Mathews at a brodeo is a legitimate
sin.
"Yo
bro, I'm so
pumped for the brodeo tonight, I know that I could get with a couple chicks"
"
Yea same, I hope I do too bra"
