What does “먹튀” mean in Korean?

먹튀 is built from 먹다 (“eat”) plus 튀다 (“to bolt / dash off”), squashed into one punchy slang word. It labels anyone who takes something and vanishes without paying or delivering: a diner who skips the bill, a borrower who never repays, a shady site that pockets your money and folds. The verb form 먹튀하다 turns it into an action — exactly what the runaway customer here does after the repair.

먹튀 (먹고 튀다, “eat and run”) started as casual internet slang and is now everywhere online — especially for scam gambling and shopping sites that take deposits then disappear, the so-called 먹튀 사이트. In the clip the mechanic finishes a pricey repair, the owner sprints off without paying, and the pursuers brand him 먹튀한 남자 — “the guy who ate and ran.” It’s informal and accusatory, so you’ll see it in comments, reviews, and complaints, not in polite or formal speech.
