Bowel Movement (on) Titties: The act of defecating on a woman's breasts prior to, or during the act of sexual intercourse. See Cleveland Steamer.

This acronym is particularly useful in mixed company, or in public.

The phrase developed in a Salt Lake City, UT Subway restaurant when trying to express the attractiveness of one of the cashiers, while not trying to use the phrase "she is so hot, I'd shit on her chest" in public. One of the sandwiches being ordered at the time was the Italian BMT, and the acronym seemed appropriate and was put into use.
Man, she is so hot I would *totally* BMT on her.

I always thought a BMT was a bacon-mayo-tomato sandwich. It used to stand for Brooklyn-Manhattan Transit and it seems to be the reason to name the sub that way. Now at the Subway restaurants they say it stands for Biggest, Meatiest and Tastiest. One of the attendants told me it would be the name of 3 boroughs, which only makes sense if you call Bronx "The Bronx". It makes me wonder what a hell on earth would be a BLT...
- Please, can you give me an Italian BMT with a B for BACON instead of BROOKLYN?
