sill the chits

Pissing out the window, especially upon anyone from Chicago.

Man from CA: When Chichy left, I thought he told me to "Chill the shit".
Man from NY: Why did you pee on him?
Man from CA: Better than throwing that frozen shit on him, right?
Man from NY: Waddaya call what you do?
Man from CA: Sill the Chits.
Man from NY: Too clever, lets get some shitty California pizza.
