The act of hanging out with your bro's (generally frat dudes). It often entails talk of previous conquests and how awesome their fraternity is. Many of these conversations happen after a night out at bars and consist of reminiscing about the amazing frativities of the past years and the lack of time left in the frat.
Tosh: Ryan, we spent two hours last night fratting after getting home from the bars.
Ryan: Dude, I know I graduate this year and it won't be the same.
Patterson: Yea, you all did some serious bro-ing last night!
