남친

“남친 (namchin)” is a shortened slang term in Korean meaning “boyfriend.”

Shortened from '남'자'친'구 (boyfriend).

which literally means:

• 남자 = man / male

• 친구 = friend

So together it means “male friend,” but in modern usage it specifically refers to a romantic boyfriend.

In everyday Korean texting or casual speech, people shorten it to 남친 (namchin) for convenience, especially on social media or chat apps.
