Pirate's Scratch
Occurs during a game of billiards, in which your opponent(s) accidentally hits the cue (white) ball into a pocket. You then proclaim the term "Pirate's Scratch." If delivered repetitively with the proper tone and dialect, your opponent will become extremely aggrivated. The need to know exactly what a "Pirate's Scratch" is will become overwhelming. At this point, you must make a habit of putting the word "Pirate" in front of every pool term. Oh yeah, it doesn't mean anything.
"I'm gonna combo the one to nine in the corner..."
(Cue ball falls into side pocket)
"Arrrrgh. That be a Pirate's Scratch."
