The feeling you get when something is so crappy that it's crappiness becomes almost a good thing in an explosion of crappiness. In other words, orgasmically crappy.
Craigism /'Craəgısəm/: a singular word ment to have humour derived from it that is expressed in a loud manner repetitively. It is often accompanied by a sound such as "YAW".
"His Hexican wife gave him a crabgasm, didya hear?"
"Huh?"
"Yeah, she slowly eased it within his inner sanctum until he came furiously upon it's hot red armor."
"That's hot."
When you get an orgasm/excited over something that isn't really special
Fx.
You're an Italian, you get spaghetti and meatballs every second day.
And mom screams "The spaghetti is ready" and you get a craygasm.
Because you've gotten so much spaghetti is isn't special.
