The Callaghan Clap 

Originated by the man, the myth, the legend, Bill Callaghan. The Clap is what Bill uses to signify that the drink is on him at the wonderful JJ Bubbles. If you're not paying attention, Bill will wait and start to get angry that you're not acknowledging him, or he will simply give you the "Air Clap" from a distance.
We're going to Bubbles and hopefully the Callaghan Clap is in full effect.

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.
