(n.) A white tube sock that serves as a jizz recepticle following masturbation. After a series of loads have been deposited in the sock, the protein stains will harden, thus beginning the "petrification" process. Also see protein sock
1. My petrified sock has been the recipient of so many loads, it is now brown and can now stand up by itself.
