The lumberjack is a sexual finishing move, wherein a man is having sex with a woman doggie style. When the man is ready to finish, he wraps his legs around the woman and begins to chop her in the kidneys as though he were trying to chop down a tree. The goal of the Lumberjack is for the man to hang on until he finishes inside of the woman, while yelling "TIMBER!"
Eric was feeling especially kinky one night, so he decided he would pull the Lumberjack on Megan and chop that bitch down.
