shartgasm 

A shartgasm: masturbating before you have diarrhea. Cumming and making the first wet push at the same time.

I sat down an hour after indian food and decided to jerk off. I came just as the first salvo came out- what a shartgasm!!

Shitgasm 

The State of relief and euphoia just after unleshing a giant crap(or perfoming "Shock and Awe") from your body... usually accompanied by a long sigh of relaxation as your sphincter retacts to its normal state. Much like the state of relaxation after an orgasm... kinda...

"I shitgasmed twice already this morning... its gonna be a good day!"

shitasmia 

A blend of vertigo, disgust, anger and embarrassment, such as felt when watching one of Microsoft's spectacularly cringeworthy "Windows 7 Launch Party" videos.

Coined by Charlie Brooker writing for the Guardian.

Did you see Microsoft's Windows 7 launch party video? It was shitasmic!

I have the most awful case of shitasmia from cringing so much at the goofy acting in that show.
