Get the U mad bro? mug.
A phrase commonly used in games in which one player is intentionally doing something in order to piss another off. This phrase is then repeated multiple times as a way of pissing off the offended player, causing them to want to reach through their screen and strangle the 10 year old kid on the other side and leaving the occasional gaping hole in one's computer, TV, etc. screen.
Offended: Dude, leave me alone.
Offending: U Mad Bro?
Offended: Seriously, leave me alone!
Offending: U Mad Bro?
Offended: Dude!
Offending: U Mad Bro? U Mad Bro? U Mad Bro?
