Anything that is used to wipe up after sex, including but not limited to: Kleenex, towels, small pets, shirts, sheets, pants, underroos, hair, socks, toothbrushes, adult diapers, etc.
Non-use of shagbag will result in a dirty shagwipe and a larger shagslick...
It can also leave crunchies in your pubes.
