"Twelvehitphobia" - a fear of 12am KST thinking that bighit will drop something.
"I'm always afraid that after 12am KST bighit will randomly drop BTS videos or something and scare the shit out of me....I guess that's why people call it 'twelvehitphobia.'"
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).
