When a man pulls his balls above his belt line (keeping his penis hidden/tucked) and raises his shirt revealing his scrotum (ususally shiny due to pressure) and says to the witness, "Check out my belt buckle..... it's Scandinavian"
Hey Dave!! Check out my new belt buckle!!!! ..... (Matt lifts shirt revealing his balls) its Scandinavian.
Dave; What the fuck dude! I don't want to see your nuts!!!!!
