When a party features Dave Matthews Band and too many popped collared, horizontally-striped polos for its own good.
You walk in to a party and overhear -
"O.A.R. is like my favorite band!"
"Did you get that shirt from American Eagle? Awesome, bro!"
"I love playing John Mayer songs on my guitar. That bro knows how to play."
Sneering at the Phish poster on the wall, you say to your friends "This party is broverloaded. Let's bail."
