when an attractive girl is very hot, but not quite a one pump
, so hot, that if you were to grasp ones penis firmly, one could only hold their load for two full strokes, or 'pumps'.
part of a rating system, one pump being the most dime babe you'll ever find, and two pump being next up, one pump being near perfect, and two pump still being VERY attractive, only with a few imperfections
not to be confused with no pump
or one pump
