Skintubation 

"An action in which one inserts their penis into the oral airway, like a laryngoscope, and places the head 3-4cm above the carina"

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

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? ; )
