The event that occurs when your sphincter and your stomach simultaneously contract so violently that you have to make the ill fated descision of whether you have to poop or vomit more at that moment. Inevitably you end up doing both at the same time which is so embarrassing that regardless of your age a call to you mom is placed.
Last night I drank so much that I ended vooping in my girlfriend's parent's toilet and tub. Twenty minutes later my mom showed up with a towel ... why won't she call back?
