This is a cute thread, but it died a year and a half ago. Let's restart it
The next person will have a diapered movie night! They will start the dare by drinking 2 glasses of water, diapering up, and putting on their favorite film. During the movie, they will need to drink an additional glass of water every 10 minutes.
If they hold their pee for the entire film, then they can use the potty like a big kid. If not, then they'll need to stay in that diaper for 6 hours, using it for all intended purposes.
