A sexual position, the Fart Knocker is achieved when a man is engaging in breast coitus with a Woman but is facing the opposite direction so the man's anus is hovering above the Woman's face. While pumping the breasts, the Woman sticks out her tongue which brushes the man's anus as he humps her breasts.

A fartknocker is a person that is so lame they do not appreciate a good fart. They 'knock' or 'put down' the idea of farting and enjoying it; which makes them a total loser.

Someone who is being a jerk. They pick on people over and over again or do something rash and without thinking.

Or the original meaning, someone who farts often and announces it.
