Davenport Steamer

Verb - The act of smashing out someone's windshield then squatting and taking a shit on their dashboard. This probably originated in Davenport, IA where people do this all the time.

That fucker cut me off, so I followed him to the restaurant and did a Davenport Steamer on his new ride. Imagine the look on his face when he comes out of the restaurant with his girl and sees his windshield smashed out and a fresh shit loaf on his dashboard!
