NASF 

Needs a second flush, like when you go to the bathroom and the fat ass before you left some of their shit behind so you have to flush it before you can go. It's what you call people that god made on accident.

"Oh my God, Christina Aguilera... She's so fucking ugly and she can't sing... NASF!"
