Oh Shit Bro or Oh Shit Brother or Oh Shit Boy or Oh Shit Bitch- This phrase can be used several ways and change meaning depending on the situation. It could be from some exciting event or a close call. Could also be used in place of OMG for those guys who are fed up with this phrase (too feminine). OSB is a little more masculine. Usually used at the beginning of a sentence to show excitement.
OSB, that was a close call!
OSB, did you see that!?
WTF!? OSB, you have got to be kidding me! I do not believe it!
OSB, someone stole my car!

OSB, aka "One Sentient Being", is a term describing two or more people who "connect brainwaves". For example, this happens when they say, do, text, or think the same thing at the same time.
Person 1: I really hate this tweet.
Person 2: Whoa, I was gonna say that, 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.

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.
