Likegasm 

When a user of Facebook "likes" multiple consecutive posts in a comment thread.

(Lots of likes by one person down the thread.)
"Dude, did you just Likegasm?"
"Yeah, all over the place."

Lifegasm 

A superlative life experience; instills the sensation as if one were perpetually cumming.

Having a pirate ship battle with your best friend would produce a lifegasm.

lifegasm 

Similar to an orgasm, a lifegasm is more or less an epiphany in which one has a sudden realization causing them to have this EXTREMELY good sensation.

Oh gawd, Samus is actually a girl?! I think I just had a lifegasm.

Oh wtf... Bridget's a GUY?! -lifegasms anyway-
