An ugly, old, balding white man. If your name is Jeff, hate yourself. Nothing alive likes you, especially your ex-wife. Your dreams are as broken as the car you drive. An old guy with feminine hips and a sickled back. The surface area of your forehead should be measured by science because it is physically impossible in size (unlike your penis). White as the day is bright. Nobody likes you (including the one parent that is living). If you feel insecure, you have every reason to be. People talk behind your back, and you know it. You desperately need a shower and revenge on whoever named you.

Tanner: What is it?
Bob: Jeff! It means kill yourself.

When Jeff requests a song in Nashville and upon hearing the song being played, Janet responds, “I don’t even like Dave Matthew’s, who requested this?”, and it was Jeff…
And all the friends respond - Good Job Jeff!
