osb

An "over sized baby"

An adult who looks and behaves like an oversized baby. One who exudes OSBisms, that is, the characteristics of an infant.

George Dawes in Shooting Stars.

Many examples of OSBs are apparent in todays workplace. See gibbering fatty OSBs with no hair and shiny heads, that babble and whine all day. Fuelled on sugar and coke these sloths portray the characteristic behaviour of an oversized baby (OSB).

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.
