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!
