Whoo-dee-hey
It's a completely nonsensical word that doesn't mean anything to anyone except me. Not even sure when, where, or how I came up with it.
It's a word I use, mostly to myself, when I think the person I'm talking to has shut themselves off to reason, is just spouting nonsense, and I'd probably be better off just letting them.
Example:
Me: "No problem, the cafeteria is just west of where we are *points west*.
Them: "That isnt West, West is that way *points east"*
Me: "No, actually, West is that way *points West*
Them: "Then how come the West Wing of the library is over there"? *points East*
Me: "Because we're west of the library. The whole library is east of us, West Wing and all".
Them: *rolls-eyes condescendingly* "Oh I see: you know more about the library then the people who built it" *smirk smirk*
Me: "Well whoo-dee-hey! by God you're right! The cafeteria is that way". *points towards the women's gymnasium*
