A sexual act involving a string of graphic and unlikely moves and/or fetishes, often including fecal matter or second-hand semen between two gay men.
A "Rusty Venture" is when two men and a rhinoceros get slathered in butter. The first man licks the second man's anus, then helps him mount the rhinoceros' horn while masturbating himself, nearly to orgasm. Then the second gay man induces vomiting while the first man ejaculates and excretes simultaneously. Finally, the second man climbs down from the rhinoceros' horn and rolls around in the semen, excrement, and vomit mixture with the first man, before they both perform fellatio on the rhinoceros.
