Basically it's when you motor-boat someones butthole. A sexual partner places his/her lips inside the butt crack of their partner and exhails forcefully while turning head from side to side. This will generate a motor-boat like sound.

Cherry Boiler

A fart after drinking 12 or more cherry cokes in a day. The smell is that of rotten cherry coke that has been boiled.

Tyler: Damn, dude! I just ripped ass, it reeks!
Brett: You’ve been pounding cherry cokes all night, fella. Is it a cherry boiler?

Jeremy: I’ve been slamming cherry cokes and ripping cherry boilers all day, fellas. My jeans stink like molten ass.

slow lobster boil

When the hot water you’re in is getting hotter so slowly that you don’t grasp the danger you’re in until it’s too late.

I was just a few steps away from death when I was pulled from that slow lobster boil of a workplace.
