Verb, the act of lubing up an athletic tube sock and inserting the male member for sexual stimulation. A sockfucker may choose to perform the act manually or may choose to have a partner stimulate the sock. Low Cut socks are disfavored except by short dicked individuals.
Don't wash that sock after the game, I'm into sockfucking and your natural oils are better than you greezy fuck.
