skin tube 

Slang for anyone who's a human. Mostly used by non-humans who tend not to have skin.

Hey, skin tube! Clean up my shit!"

skin tube 

the secret ring of flesh that comes out from inside your ass and hugs your turd goodbye.

1) My skin tube got kinda torn and bloody after i ate all that fiber and meat. It hurts right now.
2) I want to pierce my skin tube. How much will it cost? ; )
