The act of having have your ass handed to you (usually in a verbal manner); in other words, to get totally pwned.
Named after the infamous Glenn Beck after getting his ass handed to him by Whoopi Goldberg and Barbara Walters on The View
Jake: Dude I went to holler at that hot chic and I was totally Glenn Becked
John: Yeah dude...you are like a total loser man. Chic Glenn Becked you...you should go sit in a corner and cry dude.
To ask someone to prove a negative.
'glenn-becked': as in being asked to disprove a negative which originated in a lie.
President Barack Obama was 'glenn-becked' when he was accused or being a racist by Beck, or having to go to the trouble to disprove something patently false, as was the claim that he was not a 'native born' citizen, the lie was first thrown in planet 'Right Wing' back in the 2008 Presidential campaign.
The claim was totally proved as spurious, but the damage was already done, right winger extremists who listen to these shock jocks, Beck, Limbaugh, Savage, et al, wholeheartedly believed the lie and have been repeating it ever since.
So, Obama has been 'Glenn-Becked' several times.
Coming full circle, Glenn Beck himself is being 'glenn-becked' by being asked that he disprove the internet rumor that he raped and killed a girl in 1990
To make a connection based on logical fallacies.
Jon Stewart "Glenn Becked" Sarah Palin last night - he determined she's a Russian spy because she likes to wear red, chases moose (like Natasha on The Rocky and Bullwinkle Show) and calls herself a momma grizzly (Russia's symbol is the bear!).
