A event that starts out as a small kickback but before you know it There's a guy riding a horse naked, people shotgunning 24 oz beers, three girls making out and all the bathrooms are full of people either fucking or puking or both. It's a god damn Catalina wine mixer.

A Helicopter expo from the film 'Step Brothers'. Also known as the 'Fucking Catalina Wine Mixer'.

When something is very unexpected and awesome

The sexual act of inserting 3 or more red grapes into the vaginal canal and using your penis to juice the grapes into a liquid state for consumption afterward. Once fully mixed a hardy POW is yelled to signify completion.

While watching Facebook videos of Matt Bellassai, and while drinking a fine merlot, the man puts a cork in his ass and swings his fully erect penis around like a helicopter rotor...all while listening to Por Ti Vilare by Will Ferrell.

Slang. It’s when a woman puts a grape in her vagina and the guy says POP!
