A person (Chinaman or not) who pisses on a rug which may or may not "tie the room together", thus rendering the rug useless.
==================

It's a shame that the Chinaman pissed on your rug, Dude... It really tied the room together.

==================

BRANDT: He suspects that the culprits might be the very people who, uh, soiled your rug, and you're in a unique position to confirm or, uh, disconfirm that suspicion.

DUDE: So he thinks it's the carpet-pissers, huh?

BRANDT: Well Dude, we just don't know.
