A dirty rag - A smelly sock or dish rag used to cool down pipes in a trap

A smelly sock or dish rag used to cool down pipes in a trap house and smells like a dead raccoon.

My brother used his sock to cool down the pipes and it stank like a dead raccoon.

My mom used a dish rag and it smelled like old soup.

My friend used a sock and it stank like a gym floor.
