아점 ~ brunch
It comes from combining 아 from 아침 식시 (breakfast) with 점 from 점심 식사 (lunch)
내일은 아점을 먹을까요? ~ do you want to have brunch tomorrow?
A less “official” term which I find funny is 점저 which is a combination of 점심 식사 and 저녁 식사. This is basically a late lunch/ an early dinner. As said, it is not an official word, but something that young people might use among each other. My language partner and her friends might use it if going out for a late lunch, but she didn’t exactly want me to pick up that term – so naturally it is now deposited in the “never forget” area of my brain 😀
