MWF 

Morning Wood Fantasy.
You know, when you wake up and you're horny and you jack off. The MWF is the thing you think about whilst you do it.

1: "Dude, I had the weirdest MWF this morning. In it, I was like--"
2: "Please, no. Shut up. Now."
1: "--and then she was rubbing whipped cream on my nipples.... dude, what are you doing?"
2 yanks a sign post out of the concrete and breaks in the front of 1's skull.
2: "SHUT UP!!!"
