The word "trufer" is used as a pejorative to describe 9/11 conspiracy loons, also known as truther(s), because they love to parade around with stupid chants and piss people off with their psycho babble.
Trufer: "WHAT DO WE WANT? TRUTH! WHEN DO WE WANT IT? NOW!"

Sane person: "Jesus. It's like their religion. If they spent as much time shouting and passing out pamphlets they made at Kinkos as they did actually trying to model the building collapse like Penn State University did, people might care."
