This is a pretty simple sex move. Started by shitting in your partners mouth, then receiving a blow job. Then you kick them in the stomach. The mixture of shit, cum, and vomit create a substance similar to the Manhattan sewers.
“ Sis what happened last night you look rough? ”
“ I was with a guy last night, and he performed a Manhattan sewer.”

A flatuation that has a distinguished aroma of sewer gas. The smell is usually so vile, as to cause to relieving party to crawl a way from one's own ass.

A plumber's term for a flushed tampon, after having clogged a drainpipe for some time, the tampon collects clods of hair and other refuse, causing it to resemble a dirty furry thing with a tail.
I wish these bitches would stop flushing their goddamn tampons.. if I have to plunge for one more sewer mouse...
