When someone takes a piss in a public bin; toilet, outdoor or otherwise.
Balcon worker: "I'm sick of cleaning piss out of this bin, fuck you Thomas, ya' big Bin-Pisser!"
n. 1. An angry Italian person.
n. 2. A chef who puts their bodily fluids in the food they cook (i.e. spitting in it, urinating in it, farting on it).
n. 3. Someone who literally urinates spaghetti. When they have to pee, instead of urine coming out of their "part", spaghetti does.
I don't usually tip the waiters or cooks at this restaurant. I might have to stop coming here cause I don't know if the chefs are spaghetti-pissers or not.
Someone you consistently have sex with. Could be friends with benefits, or your significant other.
I have been hanging out with Mary so much we decided to become pisser pals.
