Blockers is a story of three girls who make a pact to lose their virginity on prom night. When their parents get wind of the idea, they set out to stop them.
About 2/3 of the way in(sorry I don't have images or exact times but this one is still in theatres), the girls and their prom dates are fleeing a party that was busted by the cops. Since they've been partying, the sudden burst of activity makes one of them sick. Soon, everyone in the car is vomiting. I'm pretty sure there's some cgi vomit in the mix at one point.
