Term used by some men to indicate that they believe an otherwise very attractive woman has been given extra "points" or "bumps" up a scale by other men, thus grading them higher in the Hottie Scale (of 1 to 10) then they should be.
Term often used by sexually-frustrated males.
Dude: Man, she is HOT!
Dud: Oh, you are just giving her bumpage, she ain't that great.
