Originating in America, a Mannheim Steamroller is a sexual act that presents itself as having German roots. This act can be between a man and a woman or, in some cases, two men. The receiving partner first defecates while neglecting to wipe. After that, the man initiates anal sex, using the fresh poo as lubrication. As the grand finale approaches, the man pulls out and "rolls" his member on the upper lip region, leaving a streak of poo and semen, slightly resembling Hitler's mustache.
Man: during the holiday season, I love to give my girlfriend the gift of Mannheim Steamroller.
Friend: you mean that lame musical group?!?
Man: hell no! I mean THE Mannheim Steamroller - the single greatest sexual act in the whole wide world!

Similar to the Stairway to Heaven, but instead of rusty trombones up and down the staircase, it is a daisy-chain of people doing Cleveland Steamers on each other. Extra points if you can work the staircase in sequence.

If, after anal sex, then man finds feces on his penis, he uses it to write on his partner's back as revenge.

"Awwwww, did you Mannheim Steamroller me?"

Verb
From the Latin root Manhemium Stipula Volutor, is of Germanic origin hailing from the bathouses close to the Danube River.
The term is the act of practicing anal sex in the saunas which would soften up the fecal matter and open the pores of the skin. The penis was first used to align the innards and guide the fecal matter around the O-ring for lubrication so that next, two openhanded arms could enter effortlessly, similar to a Push-Pop. Upon attaining a full-armed fecal gloving, the arms are then removed and then trundled over and over in rotation across the small of the back, thus creating a brand new blacktop surface upon which, ejaculate can then be deposited. The odor was lifted by the steam rooms and and would penetrate outside the bathhouses requiring it to be banned as even one instance was rumored to be so heinous that the odor of least 30 pre-fucked butts could be smelled for 1600 meters.
The act was most commonly performed between two men as the luxury of co-ed saunas was popular at the time. It can be performed with one arm in the receiver, however the other arm must be inside of another receiver and both arms must still trundle over a single person.

I was at Golden Door Spa and two guys were doing a Mannheim Steamroller in the saunas. I almost vomited from the smell but I had to drop a load on that freshly rolled blacktop.
