While performing vaginal sex in the missionary position, a door knocker is the act of the man's ball sack gently tapping against the woman's butthole during each thrust. A play on the phrase, "he's knocking on the back door." In which a man suggests or non-verbally asks a woman if he can perform anal sex by tapping her butthole with his penis.
I was with Ron last night. He could not leave that door knocker alone!

Not what the name really seems. Should be re-worded to "nut knocker" but, what the hell, right? So the door/nut knocker is a sex move where as the women (or man) is providing hand or oral pleasure to the penis when the giver grabs the sack and starts beating it against the gouch, like a door knocker.
KRISTY TABING gives an awesome door knocker...i bet she practices..
