A playful "yaminjeongeum" (a Korean wordplay style that reinterprets how hangul letters visually look) term for "bibimmyeon" (spicy cold mixed noodles). The hangul characters of "비빔면" (bibimmyeon), when their shapes are read differently, visually resemble "네넴띤" (nenemttin) — a purely visual letter-swap pun with no real meaning.
