Term for a side effect of morbid obesity. Coined by TakeAKnee.net. Pillow Taint is similar to a moose knuckle or a camel toe, but puffier and gender-neutral.
Pillow Taint occurs when a morbidly obese person sits down and the entire crotch of their pants is stretched to nearly bursting with flab.
Usually, the volume of flesh trapped in the crotch area is so great that the obese person is unable to cross (or sometimes even close) their legs.
The situation resembles a normal person with an overstuffed pillow packed down the crotch of their pants. Thus the name: Pillow Taint.
"Jesus... Did you get a look at that fattie over there? I couldn't even tell if it's a man or a woman!"
"I know... I tried to check the crotch bulge, but all I saw was a textbook case of pillow taint."
