A nutjob conspiracy theorist who believes President Barack Obama was not born in the United States.
Dude 1: "The birfers are so desperate to prove that Obama wasn't born American that they resort to forging birth certificates."

Dude 2: "Yeah. Birfers are non-stop comedy."

Crazy people who think Barack Obama was not born in Hawaii, USA. They Claim his Birth Certificate (COLB) is a fake, he was born in Kenya, making him ineligible to be President.
Groups that fall under Birfers: PUMA, Fringe Right-wing Blogs, Conspiracy people, Bigots, Sore Losers and mentally unstable.
