TIL about "four-letter word" as an ESL speaker. If anyone else is confused about the linguistic compression algorithm that squeezes "scheduling" into just four letters, the magic is, of course, profanity! And "four-letter word" seems to be a polite way of saying something is or can become a PITA.
yeah calling something a "four-letter word" is intended to evoke the idea that, people react negatively upon merely hearing the word (as though it were an expletive)
