Blue Flames is an armor effect in Halo: Reach that was exclusive only to Bungie employees. Now everybody has blue flames because of the Bungie Mobile app. It was cool before, but now it is just a noob detector because most BKs wear it. It is certainly the Hayabusa of Halo: Reach.
Noob:H3y guy$ ch3ck 0ut m3h b1ue f1@mes
Me:You are a Goddamn noob. Blue flames suck ass. You are probably an armor lock whore. By the way, talking like that only makes you sound like a poor, uneducated inner-city kid.

The ignition of a fart.

To fart while holding a lit lighter a few inches from ones butt-hole. "You should have been there last night, when Jonny lit up a blue flame and burned his asshole"
