현웃 (hyeonut) — An actual laugh out loud.

Lesson 83 in our Korean Slang series, adapted from Korean Your Teacher Doesn’t Teach You by Injin Hwang. This expression appears in the book’s shortened expressions section.
What 현웃 means
When a photo or message makes you physically laugh, 현웃 emphasizes that it was more than typing a polite laughter marker. It shortens 현실 웃음. The situation and tone help determine how natural the expression sounds.
A short conversation
A: 이 고양이 사진 봐.
B: 현웃 터졌어!
A: Look at this cat photo.
B: I actually laughed out loud!
Use it with care
Mostly appears in online reactions. Do not confuse a typed claim of 현웃 with proof of how someone reacted in real life.
A neutral or polite alternative: 정말 소리 내어 웃었어요. — I really laughed aloud.
Try it yourself
Does 현웃 mean a silent, polite smile?
Answer: No. It suggests an actual laugh. Read the Korean exchange aloud, then replace one detail with something from your own life.
