Pants Icing 

the crusty, white stail in a woman's pants.

Distinctly noticable by it's texture and great smell.

John was turned on as he noticed pants icing while removing her undergarments

"Wow!, that's a whole load of pants icing"

Panty icing

The snail trail of slime left in the guesset of a girls panties. Goes crusty after a while.

When I took off her knickers, you should’ve seen the panty icing in them!
