After the woman is humiliated, the man takes a steamin shit into the pile of vomit. They start to kiss very passionately and roll into it. They have now steam rolled it.

A blunt wrap(Swishers, Optimos) is rolled with marijuana and cut up into small little pieces, then individually smoked out of a bong. Usually one piece per person.
