When a group of close friends who consider themselves to be like brothers all "fall out" and go there separate ways for varying reasons.
if 6 friends fall in love with the same girl and everyone fights over her and eventually everyone hates everyone then that girl has caused a brolapse.

The reinsertion of organs by one's bro when a weightlifter experiences a prolapse during a monster set of squats. Usually accompanied by a fist bump and reassertion of "beast-mode" status.
"Matt tried to go beast mode on a 1,200 squat but luckily I was there to brolapse him dude."

The average bro that mooches off his friends and does nothing than play Halo, CoD, and WoW or likes to play drinking games while online. The rules would be who ever gets a headshot or gets a beatdown will drink a shot. The biggest douche game ever.
