'Depending on how I handle it, things could go good or bad' — First reply: 'Retreat'

An anonymous post at 1:04 AM reads: 'Hey, depending on how I act, this could turn out good OR bad, what do I even call this situation'

The poster adds 'ㅈㄱㄴ' — Korean shorthand for 'no further explanation needed' (i.e. self-explanatory).

The very first comment, also at 1:04 AM, simply says: '수련회' — meaning 'retreat' (as in a school/church retreat). Someone immediately knew EXACTLY what kind of situation this is without any context. The speed and confidence of that one-word answer is the whole joke.
