A sexual act involving stuffing your testicles up your anus during a blowjob only to violently fart them out and swing them forward at your partner's chin and or mouth at the point of orgasm.

I gave her the old rusty wrecking ball after she sucked me off.

Rusty Wrecking Ball Supreme

The act of shoving your balls up your asshole, then getting a girl to suck ur dick, and while she's not paying attention you fart your poopy nutsack out of your ass so it swings forward hits her in the face. A properly executed Rusty Wrecking Ball Supreme involves trying your best to not shit on the floor during the act of farting your balls out of your asshole.

NOTE: To impress the ladies even more, it is common practice to get your penis AND your ballsack in your own asshole.
