What does “ssaeppajige” mean in Korean?

쌔빠지게 comes from 혀가 빠지다, “for the tongue to fall out,” worn down in the southern dialects into 쌔빠지다. It marks effort pushed past exhaustion: 쌔빠지게 고생했다, “I worked myself into the ground.” It is colloquial and a little rough, so keep it for friends and complaints rather than anything official.

The clip is a drama steeped in Jeolla speech, where a neighbour tells an amnesia patient that the man claiming to be her boyfriend 쌔빠지게 쌔빠지게 찾아다녔다 — hunted for her until he dropped. The scene is full of regional markers: 그짝 for 그쪽, 기둘려봐 for 기다려봐, sentence endings in -는디 and -벼. Dictionaries list the word as 새빠지다; the tensed 쌔- spelling is how people write it.
