OSB

OSB (Op-Sex Break) This is when you go on a break from a member of the opposite sex. Until you find the right person, you do this normally after a slutty streak to regain dignity.

OSB

Obnoxious Sarcastic Bitch

I'm getting really tired of that OSB my brother married slamming all of our family members every chance she gets; then she's so proud of being an OSB she applies the suffix to her signature.

OSB

An acronym for Oh Shit Button. Used in MMOs, OSBs are OGCD (off global cooldown) instant-cast heals that can be used when the tank unexpectedly takes a massive loss in health.

The tank stood in the telegraph and I had to use my OSB to keep them from dying.
