For instance, given the heady mix of excitement, junk food and fast rides on offer at Disney resorts, unfortunately vomiting can’t be an irregular occurrence at the park. As such, cast members have a couple of secret codes at their disposal for this eventually. They euphemistically call it a “protein spill” or a “code V.”
Apparently, a “code V” can be more generally applied to all kinds of messes, not just necessarily vomit. However, the use of such a phrase will certainly save any embarrassment on behalf of the sick visitor. Furthermore, hearing that there’s been a “protein spill” also tells the cleaning team that they’re required.
