A dance move that some females like to consider fun but males despise due to the growing tightness of their pants.
Girls use this move to entice men, and make them assume that the girl wants to take it to the bedroom. Men do not be fooled, the girl just wants to satisfy an itch in her pants and move on. She will not sleep with you, so strap on that jock strap before you go on the dance floor to protect yourself from the hump da bump.
Unsuspecting male: "Dude, look at those girls grinding, I would love to get in there and make a sandwich"
Smart male: "don't do it bro, they will totally hump da bump you and leave you dry as a bone"
