hump daddy

When your boyfriend only humps you during sex and nothing else, aka no special positions that all girls(or boys) want. This will probably happen when you want sex but he doesn't. This usually means he is bored with your orgasms or sex moves. It could also imply he doesn't want to have sex with you for a long amount of time.

Tracy: "He doesn't put me in the position I like it anymore! I want to feel special, not a booty call!"
Mary: "OMG! What a hump daddy !!"
