Watch Ya Mouth
Watch Ya' Mouth contains a bunch of mouthguards and more than nine hundred phrases on 143 cards that you will find extremely challenging to say while sporting a mouthguard. Can you communicate clearly enough that others will guess what you're trying to say?
The game is designed to play in teams, usually of two. One person wears a cheek retractor similar to what you get at a dentist, then they read a phrase on a card with the equipment in their mouth. Their teammate(s) are supposed to try and repeat the phrase correctly back (without the retractors).
The team with the most correct answers wins.
