grierson 

The act of causing rapid evacuation of a room or other confined space by floating a particularly nasty air biscuit. Most commonly, a grierson requires the assistance of a tarka for maximal effect. The word is derives from the name of a rotund large-eared red-headed gentleman scholar of an unathletic nature (not to be confused with a waby), who claimed to be able to clear the audience of a 300-seat lecture theatre in 10 seconds.
From the Philadelphia Enquirer, 23rd March 2004: Mass panic ensued after shouts of "grierson, grierson" were heard in the darkened room. Firemen with breathing apparatus recovered the bodies of 18 of the deceased several hours later.

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.
