Pseudo-incest 

Sex with someone with a familial relationship, but no blood relationship. Sometimes treated as incest in the law, but not as much of a taboo subject in common society.

"Dude, she's not my mom! She just married my father."
"So that's pseudo-incest. Still illegal in this state."

When someone farts into another persons butt. The other person mixes the fart around inside them, then farts it back out. It is a fart within a fart.

Ben: "I love you Sharon, but I don't think I'm ready for kids yet."
Sharon: "kids!? No! I want us to make an inception fart!"
