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?

Alex- Ask to use his bathroom and do an OMP
