Rodney: I dare you to watch C-Span for two consecutive hours!
Basil: Well, I double-dare you to watch C-Span for two consecutive hours!
Rodney: Well, I triple-dog-dare you to watch C-Span for two consecutive hours!

Triple Dog Dare
It is the ultimate dare. It's for when a person rejects a regular dare, AND a double dog dare. It is a dare that you HAVE to do under any circumstances. If you don't do it you look like a weakling or a chicken.
Me: "I want you to go clean out my toilet after that massive shit I just took."
person: "No, I'm not doing that."
Me: "I triple dog dare you."
person: "Deal!"
