OMP 

Short for Opps Messy Poops.

Established-2007 thru 2008

Incorporated-2009

While you are out in public and you have to take a poop AKA a shit you must first find the nearest public restroom and go into a empty stall and make sure the restooom is fairly empty, go as if you were going to take a normal poop, but instead of sitting down you straddle the toilet and shit everywhere thus making a total mess out of the bathroom. After there is shit all over the place wipe yourself and just leave, but make sure the coast is clear!

Alex- Steven are you going to let that person talk to you like that?
Steven- Bro what should I do?
Alex- Ask to use his bathroom and do an OMP

shit dump gross nasty payback
