OSB.S. 

Refers to any dumba** statements dat claim dat waferboard is a viable building-material... we all know dat it just falls apart within a short time, especially if it gets wet a lot.

OSB.S. can also loosely refer to da inferior material itself, or to any carpentry-work/creations dat utilize it.

OSBS

osbs means "on some bullshit." This is a shorter way to write it in text.

"you're really osbs, what are you even talking about?"
