look up any word, like sex:
A gunfight between two rival gangs; specifically located behind the 7-11 in Santa Ana.
I found out she was in a rival gang so I immediately stopped talking to her and planned a gunoff.

When two buff persons of the same gender make eye contact at a beach or other public area, they are automatically bound by the law of the land to enter in a competition of flexing called simply a "gunoff".
Mark got challenged to a gunoff yesterday and lost... He's just not the same anymore.
