The same thing as a Cleveland Steamer, but with a fart added, in honor of the windy city.

Get the chicago steamer mug.
The act of presenting a wedding proposal in a steam shower, especially when the steam shower is in your parents' Chicago home.
<groom to be> After a bottle of wine and a relaxing evening lounging on the deck, the time was right to propose. I therefore gave her a Chicago Steamer in my parents' house. Naked.

<naked bride to be> Yes! You should have just written it on the glass door, however the work of art I know as your body is just as romantic.

Get the chicago steamer mug.
A girl is laying on her back, and you squat over, and put your dick in her mouth. While she is giving you head, you take a dump on her chest.
Person 1: Why do you smell like crap?
Person 2: Because my boyfriend gave me the Chicago Steamer last night.
