What your mom tells you will happen if you don't take a shower now! Your little brother notices you have been wearing the same underwear for 3 days and doesn't buy it that you have 3 pairs the same color - gray.
Teen son: Wait until I finish this game....
Mom: You said that yesterday. Do you want to get dick rot before you even get a chance to lose your virginity?
Jack: "I know, man. It just didn't make me want to avoid STDs nearly enough. That's why I think of it as dick rot. It just screams, 'This stuff is nasty and is to be avoided.' Way more to the point."
