When you take a girl/guy out for a date and don't let her/him go to the bathroom. Upon arriving back home you proceed to have anal with her/him until she/he poops on you dick. You then blow your load and the poop all over her/his back. This is the rusty part. The venture is where you remove the poop and cum without using your hands.
Man last night I took your woman out for dinner and gave her a Rusty Venture when we got home. Let me tell you the poop didn't taste nearly as good as the steak at dinner. Totally not gay though.

When you jerk off so much your dick gets all red and sore
"I'm gonna give you a Rusty Venture"

"Don't believe the hype, a Rusty Venture is the name for when you jerk off so much your dick gets all red and sore"

---Conversation between a hooker and Brock Samson in The Venture Bros season 4 episode 16, "Operation P.R.O.M."

An act which involves doing something with a result of something that comes pouring out like somebody stepped on a snack pack. then you will need to find a turkey baster, and you both will have to eat your way out of the tub.

Differs, depending on who you ask, but what is known about 'a rusty venture' is that it is a sex act, usually graphic, & by most peoples' definitions, disgusting. Although, according to one of the foremost experts in sexual conquests,(B. Samson) A Rusty Venture is not by any means an activity to be desired; "A Rusty Venture is just when you jack off enough that the skin on your dick gets raw..." An Action Johnny on the other hand....
Rusty, after being shut down at his boys' prom & washing mutant/fly/hooker/maybe assassins' blood off of his clothes, resigned himself to a night of giving himself a rusty venture in front of his computer...

When you take a girl to a big dinner, and make her pay for it but don't let her to to the bathroom. Take her home for anal sex and cum all over her back. Then eat it without using your hands.
I'm taking her out for a Rusty Venture.

When one inserts peanuts into his urethra has anal intercourse with his partner thus leaving the peanuts inside of his partner, the partner then poops the peanuts onto her partners chest. all while on top of a stuffed gorilla as your therapist watches and takes notes.

the act of jacking off a monkey while letting it shit on your partners face while she is getting dry humped by a jaguar. after the monkey blows his load all over your face you lick the poop and get your dick eaten by the jaguar. your sexual partner then gets double penetrated by the jaguar and monkey while you stick a carrot up your ass watching.
wow that rusty venture you gave me was amazing
