Roller Coaster Party

To go on a drinking spree or eating binge and then ride roller coasters. This causes the "partier" to vomit profusely. Especially fun while riding a spinning roller coaster, at which the vomit sprays in 360°

Same relevance to, "Tilt-a-hurl"

Alcoholic: "Hey man I got some beer wanna hit up the theme park?"
Friend: "Hell yeah man we can have a Roller Coaster Party!"

Dean: 65%
Sam: Whoa, didn't you get a 90 the last time?
Dean: Yeah man, roller coaster marks! :(
