The act of commentating while being Kei (BlueHairKei), or commentating in Kei-like mannerisms in Official Puyo League matches.
Such examples would be:
A match is about to end: "Is it curtains for *insert playname*?" "it's curtains folks!"
When there's no colours for miles: "An absolute drought of *insert puyo colour*! where were the *insert puyo colour*!?"
"Did you watch that puyoGB league matchyesterday, with Kei?"
"Yeah, as per usual his Keimmentary was on point!"
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
