The definition of PB varies greatly from person to person, however it is most commonly used when describing a female with gorgeous, small boobs, or "Pure boob" as it is commonly refered to.

A example of pure boob could be when one is smashed into a elevator like sardines in a can, and the woman with the pure boob's chest is smashed to your back.
Damn dude, did you see that girl?
