Pee-wee Moment

When you have to admit to something awful to prove you aren't something worse, i.e. exposing yourself as a massive pervert (gross) to prove you aren't a massive pedophile (illegal).

"Apparently Pyrocynical isn't a pedophile, but he had to post his degenerate fetish DMs to prove it."
"Yikes, what a Pee-wee moment."
