Rigorous sex act. Requires the male to vomit, deficate, and urinate into a blender. Liquify and microwave for three minutes and proceed to pour (with funnel) into the vagina of a female. The male then has vaginal intercourse with said female, pulls out right before ejaculation, spins around three times on one foot, and proceeds to finish his man-spray into the eyes of the female.
Guy 1 - "Do you remember Brenda from the other night? I totally gave her the 'Steamy Melvin'"

Guy 2 - "....Dude that's fucking gross...."
