This is when a female looks attractive in a tight pair of pants or shorts until she unzips or unbuttons them and her fat expands out of them like when you open up a can of biscuits and the dough just blows up and out of the can. The fat can appear pasty and white just like biscuit dough or it may appear in the form of another color.

Stinky pinky usually occurs after this discovery.
Dude, she looked ok until she unzipped her pants and her fat came spilling out of them. The bitch had biscuit pants!

When you shit your pants at age six, were too embarassed to tell your mom, and walked around stinky all day with a pant biscuit.
