look up any word, like hipster:
 
1.
Garrulous cluelessness.
We finally stopped the little biden by shouting "TMI! TMI!"

And who can forget?: "I mean, you got the first mainstream African-American who is articulate and bright and clean and a nice-looking guy," Biden said. "I mean, that's a storybook, man."

2.
An acceptable replacement for use of the word 'fuck' when the setting is inappropriate (such as at work or church). Originated from VP Joe Biden's idiotic flub during a nationally televised press conference introducing Obama's health insurance reform bill. It is used as diversely as the word 'fuck', but can be said in front of your grandmother.
"This is a big bidening deal!"
"Obama is really bidening the country up!"
"Biden, that hurts!"
"I can't buy a pack of smokes without running into 9 guys you bidened!"

To interrupt with a condescending grin and laugh to mask inadequacies or failures. Biden is the highest level of insulting interrupting because it mocks the other person to make them seem ridiculus.
Example: Nights debate Paul Ryan got bidened many times.

4.
To biden (v. tr.): to plagiarize. To lift wholesale from someone else's work or biography, and apply it to one's self, as if it were part of one's own past.
He then began to biden liberally from his idol's letters and accounts of his childhood, fashioning these into a new identity for himself

5.
A candidate for office so forgettable that by election day he could only inspire 2 previous definitions of his last name on the Urban Dictionary
biden, what's that? Oh, Biden! who's that?

6.
to be better than everybody at something but get no credit for it because you aren't the "rock star"
he's way more qualified for the job, he's not as young or good-looking, so he got bidened.
