Japanese abbreviation for "koko suki" (ここすき) which means "I like this bit" or "I like this part". Mainly used on video-sharing platforms like bilibili or niconico when commenting on a certain part of a video. It's also used on Youtube but you have to indicate the timestamp, as the comment system is different there.

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).
