Slang, explained by the people who actually use it.

It is an abbreviation of "suddenly pops out."

"Confession attack" — springing an unwanted love confession on someone who has no interest, leaving them awkward and uncomfortable; often used as a self-deprecating joke.

Originally from a polite gamer sign-off ("enjoy the game"), it got shortened over time and repurposed to mean "forget it" or "get lost" — often used to shut down an absurd item-trade offer or dismiss someone outright.

Short for "taking advantage of the chaos" — sneaking something in while everyone is distracted, as in 혼틈퇴근 (slipping out of work during a commotion).

Short for "default camera, no editing" — used to stress that a photo was taken with the phone's stock camera and not retouched.

"Mom's friend's son" — used for someone impossibly accomplished compared to you. The female form is "eomchindal" (mom's friend's daughter); there's also "bu-chinnam" (wife's friend's husband).
