OMFGASM 

an orgasm caused by an excessive amount of surprise or excitement

When Katie saw the Taylor Lautner in the New Moon trailer, she was so excited she had an omfgasm.

John was watching The Empire Strikes Back and when Darth Vader said he was Luke Skywalker's father, John must've had an omfgasm he was so shocked.

omfgasexscene -.- 

The awkward moment when you're watching a movie with your rents and a quiet graphicmsex scene come on. You automatically sink into your chair, blush and hope to god your parents dont say anything... In most cases you find a stupid excuse to leave room.

*Watching a great movie then suddenly a sex scene appears whilst your rent are in the room*
*you say under your breath omfgasexscene -.- while pulling an awkward face*' -.- '

OMGASP 

Basically, a combination of the two internet terms "omg", meing "Oh meh gawd!" and, well, GASP! If you need an explanation of the word GASP!, piss off that one dark guy at your school, preferably if he's goth. MAKE SURE HE IS NOT A POSER OR AN EMO, FOR THEY ARE LARKS AND ARE MADE OF PHAIL. Make fun of him so much that he either gets so angry he attempts to kills you OR he threatens you and leaves. At a good chance, you'll walk home and find that all of your family members have been killed, with their gutts and blood spread accross your dingy, small little apartment. This is truely a moment to GASP!, or even OMGASP!

(Side effects of this may include you becoming emo. If so, jump into the nearest pile of acid you can find. This may not cure it, but it sure as hell is fun to watch.)
