Self-masturbation

1. When someone performs the act of masturbation on themselves.

2. When someone acts like an arrogant twat and tries to present themselves as being smarter, cooler or more important than they actually are, typically by being boastful and/or putting other people down.

This is most often seen online, but can also happen in real life.

1. John performed a little self-masturbation when he got home to relax.

2. Hank bragging about his supposedly high IQ and over-relying on five-dollar words came across as major self-masturbation in the YouTube comments section.

Self-conscious thought

They load on to the same circuits as negative emotion! So they're the same thing!

Hym "Which is a ridiculous thing to say... It's like saying '2 Broke Girls is on the same channel as Young Sheldon! They're functionally the same show! They wouldn't be on the same channel if they weren't the same show!' and that's ridiculous. Preposterous even! So, self-conscious thoughts are still not the same as negative emotion but it would be convenient for you for people to view thinking about themselves as a negative thing."

Self Serve Clam Chowder

When you bust a fat load into her pussy then eat it out.

considered a clam chowder bread bowl if vagina is substituted with asshole

“Hey bro would you like a slice of pizza?”
“Thank you for the offer, but I am stuffed after having some Self Serve Clam Chowder this morning!”

Not self-fapping, but omg, these photos of me are so good, it drives me crazy.

Nighttime Voluntary Self-pissing

The act of pissing your pants in bed rather than walking down a dark hallway at night to risk being attack by a demon or other entity. (Springtrap is also a common one) Probably the most common childhood fear
