Underderstand

An understanding of another person's needs to have sex with a midget purely in the spirit of sexual exploration.

Person # 1: Well... I was just wondering... I mean, fat chicks are supposed to give good head... y'know...to make up for havin a nasty vag.

Soo.... I wonder what midgets are good at.
And if I have to take one for the team to figure that on out....

So be it.

Person # 2: understood. you're just being a team player

Person # 1: Exactly. Glad you underderstand.
