A growth typically located on the underside of one's testicles but always in the penile region. The growth is typically the result of many long hours of testicular abuse. In recent years, Dick Lavy has been used as an insult when referring to a particular sort of douchebag-typically a twenty-something Caucasian male. This most often refers to groups of young men who enjoy "donkey punching" or "cup checking" one another as if still in high school (or, perhaps, an ultra-douchey fraternity).
Ahhh! John, why did you piss in my tennis shoes?! You're such a Dick Lavy!
