self-potato 

When pleasuring thyself during the stance of the fetal position.

My girlfriend is so flexible, I walk in on her giving a self-potato, and I didn't mind.

Self-Invitee 

The person at the party who heard, either through facebook (eg. events, reading wall-to-wall comments) or 'a friend' that the party was happening and decided that they should invite themselves even when they have no good business being there; ruining the night for everyone.

"err who invited that guy?"
"Oh, i guess he's a self-invitee"
"Wow what a douche"
Pete Sarich.

self defecation 

Self defecation is the act of being able to make fun and/or light of yourself in an effort toward 'humanizing' yourself. Actually that is the definition of 'self deprecation' however self defecation is self deprecation BUT to the 'Nth' degree. To further explain, the antonym of being self deprecative would be 'pompous' while the antonym of being self defecative would be that of a 'complete pompous ass'.

He was trying too hard to fit in by using some self defecation humour and ended up making himself not only the butt of his own jokes, but everyone else's as well. What a complete ass, he sure went overboard.

self-cupcake 

The art of cupcaking oneself. When emitting a particularly pungent fart, one must cup one's hand around said flatulance, then release the aroma into the face. Doing it to someone else would simply be a cupcake, doing it to yourself would be a self-cupcake. This way you can unleash the true smell upon yourself.

Shit, I had eggs last night! I'll self-cupcake to see if I can smell them!

self-sucker

A self-sucker is a guy who has a long dick and is limber enough to be able to suck his own cock.

I try to stay limber by being a self-sucker now and then.
