sewer mouse 

A plumber's term for a flushed tampon, after having clogged a drainpipe for some time, the tampon collects clods of hair and other refuse, causing it to resemble a dirty furry thing with a tail.

I wish these bitches would stop flushing their goddamn tampons.. if I have to plunge for one more sewer mouse...

A used tampon, generally that which is found through plumbing work, but also can be found anywhere after discard.

I found a sewer mouse in our hiding spot in the park. Someone must have been earning their redwings.
