One prank involving vomit is the "talking sick stunt". You bring a few bottles of coloured water and some white sugar to a crowded place. First, drink one of the bottles and immediately afterward pour the sugar into your mouth. Then, quickly start to retch and make slurpy sounds. People in the vicinity will be surprised and probably disgusted, though it's really just an illusion.
