When you give a girl a whole lot of laxatives and proceed to fuck her anally.

After you finish, strap on a pair of goggles and wait patiently - face first - in front of her asshole for the ensuing explosion. After she's finished, take off the goggles. You'll look like an Alaskan coal miner!

The act in which a man 'mines' in order to extract some 'chocolate'

(a man reaches into a fellow mans anus to turd burgle steal poo )

When the man is on his hands and knees with his ass in the air while the woman eats his ass and jerks him off.

The act of eating the dirty ass of a very large person. The flaps of skin covering the area around the ass sometimes prevent it from becoming completely clean. The coal miner term is used because the face is covered in shit, much like a coal miner's face would be covered with coal.

When you pull your finger out of an asshole and it has some feces attached.

A sexual act preformed by shoving a singing canary up your partner's ass. If it stops singing, cleaning may or may not be necessary.

A girl takes a stool hardener until she becomes impacted. A guy then scoops the "coal" out of her ass into the mouth(coal car) of another girl that is waiting.
