An ambiguous sexual act that no one can agree upon. Originates from the child star Thaddeus "Rusty" Venture.

Those at the Urban Dictionary hypothesize that it has something to do with tubs and turkey basters.
The Alchemist: "Uh, Rust, you do realize that a 'Rusty Venture' is when you take your finger and run it around a guy's *** while you *** the guy off into his own ***."

Rusty: "What? My name is a sex act? When did that happen?"

Shore Leave: "Uh, like, in the '80s, and Al is way off. A Rusty Venture is when you 69 and you fill each other's *** with *** and then you turn over and blow *** into each other's ***"
