When a person is cool or fun to be around most of a time, but occasionally will turn on his or her douche
faucet and the doucheness
will just flow out without stopping.
Chris: Dude, we were at "the party" and Joey just totally turned on his douche faucet, pushed me in the pool, called Connor a fatty, paid in pennies for 18 bags of chips at the store, then mugged a chinese immigrant, molested a three year old, and punched a mexican prostitute in the face!
Nik: What a douche faucet!
Geoff: I think Joey's douche faucet is taped down in the "on" position.
