A term used to describe the act of grabbing a
female's
breast with ones hand, twisting it, and pulling on it before releasing. This is best done while yelling "doorknob" in their face.
The term doorknob was coined by a
Canadian who likened this act to that of opening a door.
"Chris'
girlfriend was being a bitch so he doorknob'd her at the party in front of everyone, he's now single."
"If a
girl kicks you in the junk you should retaliate with a doorknob."
