Get the mississippi can opener mug.
when you're being pegged in the ass by a vibrating monster dildo while trying to take a shit, but you can't shit because your ass is covered by a dildo. this causes you to vomit up all the shit, and proceed to put it in a jar and freeze it for the next day. used the next morning as a stimulant for sexual arousal and prowess.
person 1: "hey babe, you wanna try the Mississippi Can Opener tonight"
person 2: "sure, just make sure you eat up before"
