Slang, explained by the people who actually use it.

It is an abbreviation of "suddenly pops out."

Named after film director Jang Hang-jun's famously carefree attitude — a mindset of shrugging off criticism and failure instead of taking them to heart.

"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).

Short for "expectation control" — deliberately lowering your hopes so you won't be disappointed. Spread from streamers telling viewers to keep their expectations in check.

"Ditto consumption" — buying whatever a favorite influencer, celebrity, or show uses, simply copying their choices.

It is an abbreviation of "suddenly pops out."

"Freeze-dry" — wanting to preserve someone or something exactly as it is now, forever. Popularized by posts like "I want to freeze-dry my mom so she never ages."
