5'O

when you're doing something you're not supposed to be doing and someone yells 5'0 that means they're giving you a warning because you're going to get caught

say you're looking through the teachers drawer and your friend is on the look out and see's your teacher coming, he/she will yell 5'O so you can be warned and pretend like you're innocent

O gel

A topical clitoral stimulating gel, designed to help achieve or intensify female orgasm.

I put some O gel on my girlfriend last night after I had her bound to the bed, and it drove her nuts!

Katie: My vibrator just doesn't seem as great as it used to.
Grace: Have you tried using it in the shower?
Haley: Forget the hot shower, Katie, you need to get some o gel!

O/T

Acronym for "Orange Testicle". Mentioned on the Propellerhead forum as possible name for a new software synth. A sack of fun!

I've programmed some very organic, musky patches on my orange testicle(O/T).
