a condition where someone is so antsy, agitated and keyed up that (s)he gets so hyper as to fill the diaper, that is, to "shit your pants".
1. Listen to that stupid talk radio host! He's got another category of people this week he's telling lies about! He's getting hyper in the diaper again and he wants his followers to feel that way too and start a witch hunt. Someone needs to shut this stupid loudmouth up.

2. On them late night "infomercials" on TV the host often is hyper in the diaper and screams at you to call NOW!

3. Don't get so hyper in the diaper. You'll burst a blood vessel if you keep this up. Chill out!
