SEE ALSO: FIESTAR gives overseas fans a lesson on the word 'doljikgu'

The girls taught you about the Korean word 'daebak', 'deuktem', 'tteokbap', 'jjal', and 'doljikgu' before, and they're following up with a lesson on the word 'anseup'. 

As the girls explain it in three different languages, 'anseup' is a combination of 'angu' which means eye and 'seupgi' which means moisture or humidity. Thus, 'anseup' is used to refer to a situation when one's eyes get watery like they're about to cry when he or she feels depressed, sad, or pitiful.

Let's hope you don't find yourself in a situation you have to describe as 'anseup', but just in case, learn or review what it means through another fun episode of 'A-HA!' above!

It's also FIESTAR's 1 year anniversary since debut, so make sure you congratulate the girls!
