O-town

An orgasm so good it feels like a different plane of existence.

Girl 1: Hey, how was your hook-up last night?
Girl 2: Oh my god, amazing. He took me to fucking O-town last night.

O's Up

The international symbol for the best long-term Israel program known as OTZMA. Introduced in 2009, this stance, which is very similar in style to the fifth arm position in ballet, serves as a calling card for OTZMA alumni and current participants.

"O's up!"
"It's been three years, but I still got my O up!"
