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!
Similar to a Cleveland Steamer, only you shit into a container and freeze it so your partner can take it out on a hot day and let it defrost on their chest.
It's going to be really hot tomorrow, can you prepare an Alaskan Steamer for me?
Having your dog shit on someone's face because they just pissed you off that bad
I just pulled a Wheeling Steamer on our jackass neighbor!
