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.

I was just talking to this chick, enjoying my drink, and all of a sudden she grabs my fingers and shoved them in her twat!?!?!

OSB

Oh Shit Bag. An emergency bag you keep in the back of your ride in case you end up in an emergency. Usually has roadside items, and a day’s worth of food, water, First Aid, and any other emergency you could face day to day. Pretty much a bag for when shit happens. Hence the “Oh Shit” part.

This is my OSB. I don’t touch it unless I absolutely need it.
