The name of a burger unlike any other, famous in Portland Oregon.

It's a grilled cheese sandwhich for one bun, a 1/4lb angus beef patty, egg, bacon, ham, spam, the extras (lettuce tomato etc), and another grilled cheese sandwhich for the top bun.
You: Dude, that is the most redonkulous burger I've ever seen?!

Me: Yea, its the Redonkadonk.

Ridiculous. A word that, when used by the right people, is hilarious.

Otherwise the formal spelling of, redonkadonk, is derived from both redonkulous and badonkadonk; hence coupling verbal and visual absurdity together in order to portray something (emotionally and/or physically) unfathomably disturbing, amazing, or - in many cases - both.
