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 blueflame and burned his asshole"
A derogative term that borrows from both the concept of the "blue-plate special" and the practice of "blue flaming" to suggest a generic knucklehead, most likely male.
Son, you're a regular blue flame special- young, dumb and full of cum.
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
