The act of taking a shit on someones chest before during or after sex (can be used as a punishment, break up tactic or fetish act) Very similar to the Cleveland Steamer, but with the Boston Steamer, you also tea bag her with you nut-sack while taking the shit.
Bitch, shut your fuckin mouth, or i'll tape you to the bed and give you a Boston Steamer.
