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

Oh Shit Bag. An emergency bag you keep in the back of your ride in case you end up in an emergency. Usually has roadside items, and a day’s worth of food, water, First Aid, and any other emergency you could face day to day. Pretty much a bag for when shit happens. Hence the “Oh Shit” part.

This is my OSB. I don’t touch it unless I absolutely need it.
