Speak Out

A game which alows your friends and family to see if you brush your teeth.
If you don't, they'll laugh at you as you try to call a dentist.

You could also swallow someone saliva if the mouthpeices you use are not carefully washed. How fun!

Dude: Yo, you wanna play Speak Out?

Dude 2: Nah bro I'm too sensitive to the mouthpeices.

Dude: You don't brush your teeth do you.

Dude 2: Nah.
