When a man inserts his penis inside the urethra of another man using only a funnel and motor oil. It is extremely dangerous and painful, which is why it rarely exists (even in the cock and ball torture community).
Sorry I couldn't hang out last week, I was in the hospital after successfully pulling off the cleveland meatbucket with my buddy from college.
A sexual act in which one partner defecates into the other partner's mouth. Shortly after, vomiting will ensue. Whilst the "bucket" if firmly held shut, the first partner then fucks the other's mouth.
Once completed, the "bucket" will consist of Shit, Vomit, and Semen.
Dude, I took home this nasty girl last night, and you know what ?? I turned her into a mississippi mudbucket.
