O-Turn

When one sexual partner is about to reach climax before the other, and is strongly encouraged to turn back from his or her orgasm, and wait for the other partner to reach a similar level of arousal.

O on the Go

Getting an orgasm while traveling. Generally one person is driving while reaching over to finger fuck the other, but any act of O-ing while traveling would be considered an O on the Go.

"On the way to the airport I want an O on the Go. ::Insert antsy wiggling around/touching self:: "

o well

It's just another way to say "Oh well" on. You do though pronounce the "O" faster, so the "H" actually make a difference.

I didn't know that, o well o well.
