Vomit Chain Reaction

Go To

And then Frank lost it, too, joining the chunk-blowing chorus, the barf brigade, five men in a tossing boat who might have reasons to kill each other, but who, for the moment, could think about nothing except when the next retch would come, and what it would bring up.

When one character barfs, soon everyone else starts barfing as well.

This is Truth in Television, since vomiting has been known to inspire vomiting, as part of a prehistoric instinct; if someone from your tribe vomits because they ate something harmful, chances are you ate the same thing and therefore it's best if you hurl it too.

For the one person version, see Vomit Indiscretion Shot. Compare Reactive Continuous Scream. Contrast Vomit Discretion Shot. A small version of Disaster Dominoes, and a form of Brown Note.

  • In Gintama, Tama induces this when she demonstrates her internal food preparation function by vomiting out some monjayaki (A Japanese dish that looks rather reminiscent of vomit). Predictably, nobody is interested in sampling it afterward, though partly because it's still pixeled out like actual vomit.
  • Haikyuu!!: Implied in Episode 12 of season 2 where Hinata mentions throwing up on the bus ride to an inter-high volleyball tournament. Both Yamaguchi and Asahi, two of his teammates, are depicted feeling sick after witnessing the incident. They don't actually vomit, or at least it's never shown on screen.
  • In Episode 14 of Princess Connect! Re:Dive, the gang eat meat rustled up from what are later discovered to be "mouth ghosts", one of which has fur identical in coloration to something Karyl happened to be wearing. She is interrupted from her complaining about the situation by a sudden discharge of rainbow-hued vomit from her mouth — turns out the meat was poisonous. And everyone had that same meat. This trope soon follows.

  • In The Goonies, Chunk says the worst thing he ever did was start one with fake vomit in a movie theater.
    Chunk: But the worst thing I ever done... I mixed up all this fake puke at home and then I went to this movie theater, hid the puke in my jacket, climbed up to the balcony and then, t-t-then, I made a noise like this: hua-hua-hua-huaaaaaaa! And then I dumped it over the side, all over the people in the audience. And then, this was horrible, all the people started getting sick and throwing up all over each other. And I never felt so bad in my entire life!
    Jake: I'm beginning to like this kid, ma.

He enters a pie-eating contest that he knows will be attended by everyone who made fun of him, yet his goal is not to win, but to get revenge. He secretly consumes a bottle of castor oil and a raw egg before the contest, and then after briefly dominating the contest by eating several pies, he vomits. This sets off a chain reaction of vomiting in all the other contestants, officials, and spectators, successfully invoking the trope and humiliating his tormentors.

  • Causing one of these is how Buster Casey, aka Rant got his nickname. As a kid he created a haunted house with actual brains, blood and guts from a slaughterhouse. Once the other children realized what they were touching...well, apparently the onomatopoeia for hurling is "Raaannntt!"

They then stopped for some air freshener, with Ozzy buying spearmint spray to at least cover up the smell. But then Bill (who was asleep in the backseat and hadn't noticed a thing) turned out to be allergic to spearmint and once he took a whiff of it, he puked in the car too...
