look up any word, like cunt:
 
1.
A term used for what used to be a receipt of purchase or whatever piece of paper was left in a pocket prior to washing.
The subsequent product is a hard clump of white material.
Sometimes with undecipherable writing, only hinting at what useful information it used to hold.
Uh... sorry I forgot I put your number in a pair of jeans I just washed and is now a pocket fossil.
Can you gimme your number again? I promise I'll call you.
