A friend of a friend was nicknamed "No Fuck Chuck". Super good-looking guy that the girls loved...but he would never mess with them. I think we know why, but that was never confirmed.
My freshman year in college I had a guy who lived 2 rooms down from me in the dorm. Everyone called him "Buoy." Dude had Elephantiasis in his scrotum. Balls as big as a . . . you guessed it.
My nickname is Slinky. Got called a "slinky lookin mofo" in the 8th grade and it stuck. I here it everyday from everybody. Most people don't even know my real first name.
