infallible underpants

A phrase mocking any token or procedure the possession or performance of which invests a person with arbitrary authority.

It's a nod to the specific criteria necessary for the Pope to be said to be exercising Papal Infallibility -- and so be speaking for God. Without fulfilling the criteria he's just a man in a funny hat and can be as wrong any anyone else.

"I don't need to look it up. I'm wearing my infallible underpants."

"For Christ's sake Bob, you've a clipboard not infallible underpants."

Engine Underpants

Engine Underpants / ˈɛn dʒən • ˈʌn dərˌpænts /

Also known as " Creepers / ˈkri pərz / "

Any type of undergarment with a tendency to repetitively ride up your butt crack, with the power and reliability the of a steam-engine train riding the rail to the express tunnel, leaving you unhappily maneuvering it free and/or pulling it out like clockwork.

*Insert mental image of Thomas the Tank Engine Boxer-Briefs >>Here<< .*
