Disputed FrenchPreum’s !Used at the end of a long car ride to determine who will go to the bathroom first.

If you get to the very end of a long car ride and you know that multiple people want to go to the bathroom, the first one to say "preum's" (from "premier", meaning "first") will go there first. "Deuz" (from "deuxième", meaning "second") can also be used if someone missed their chance to go first but still wants to go second. It's less commonly used though.
