Buttsumption 

The eating, drinking, or ingesting of something by way of the anus.

Sometimes the insertion (but not consumption) of objects into the anus may also be referred to as buttsumption.

A term that usually accompanies anal sex with a very loose anus. The extra flaps of moist skin form a seal around the penis, acting as a plunger and sucking it inwards and onwards, deeper into the abyss.

The butt seems as though it is swallowing the penis whole.

Mark: "Hey dude, you ever had a beer enema? Gets you drunk like mad crazy!"
Paul: "Think I'll pass on that one."

Hannah: "Stuffing my bum with acorns."
Jack: "I don't think those are meant for human buttsumption."

Tom: "Hey Bro, heard you got anal from Alice last night?!"
Jerry: "Yeah. Too bad her anus was loose as a clown's pocket. Her butt almost swallowed me whole!"
Tom: "Damn, dude. Sounds like a case of penile buttsumption!"

ButtCussion 

ButtCussion: Severe fall landing directly on one's posterior axis, causing severe pain to the point of nausea - as in a "concussion of the butt." Falling and landing directly on the gluteus maximus or worse, a direct blow to the coccyx, with pain so severe that it causes concussion-like symptoms.

He jumped up into the air over the frozen swimming pool, cannonball-style with ass pointed down and knees up, thinking the ice would break and he would polar bear it but the ice did not break - Total Buttcussion!!

butt cum 

n. a word used to describe the semen that leaks out of the butthole when having bareback anal sex; often leaks out of a gay man's butt

After I came in his butt, I opened my mouth and let the butt cum drip inside.

I wanted to fill him with butt cum, but he made me use a condom.
