OSB 

An acronym for Oh Shit Button. Used in MMOs, OSBs are OGCD (off global cooldown) instant-cast heals that can be used when the tank unexpectedly takes a massive loss in health.

The tank stood in the telegraph and I had to use my OSB to keep them from dying.

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.

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.

Ozzy Osbourne 

Known as The Ozzman, or the Blizzard, Ozzy Osbourne as one of the creators of Heavy Metal. In the late 60s him and 3 other guys set out to make a band known as Black Sabbath(also known as the first ever Heavy metal band). Ozzy led them out of England and into much bigger places. In the mid 70s the band kicked out The Ozzman, and he had to go on his own. In 1980 he came out with his first CD, "The Blizzard of Ozz". Ever since then he has hit some high and low spots. At the moment he has a show on MTV. Ozzy Osbourne's songs > most songs.

"Ozzy Osbourne, the Godfather of Heavy Metal."
