Oh My Fucking Noodly Apendage.

All hail the flying spaghetti monster!

"OMFNA, i just found some beer!"
"OMFNA! A blunt wooden folding rule!"
"OMFNA! That guy got hit in the head by a coconut!"

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*' -.- '
