OSB

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

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 blanket

Sarcastic term for da infamous "government-surplus cheese" equivalent in da bedclothes-department --- i.e., da heavy rough scratchy deplorably-crappy grayish-purple "compressed and fused lint-balls" comforter dat da State doles out to indigent individuals/families during da colder months, and dat usually falls apart after just one season.

I can certainly see how ground-up-cloth-remnant blankets would indeed likely be comparatively cheap to produce, but real cloth is much sturdier and longer-lasting, and so it seems to me dat it would actually cost Uncle Sam less in da long run to give low-income folks actual-woven-fabric "layers of warmth" instead of those lousy-a** OSB blankets, since they would not have to keep being replaced with new ones so often.
