What does 삼귀다 mean?
삼귀다 (samgwida) means: The 'talking' stage before officially dating.
A clever pun on '사귀다' (to date). Since the '사' in '사귀다' sounds like the number 4 (사), people replaced it with '삼' (number 3) to mean the stage right before officially dating. Very casual slang among teens and young adults.
How it's actually used
- 요즘 그 사람이랑 매일 연락하는데, 삼귀는 중인 것 같아.
I'm texting that person every day lately; I think we're in the 'talking' stage.
