Phonetic loan from English 'yuppie' (
雅痞 ≈ ya-pee). Cleverly chosen characters:
雅 (elegant/refined) +
痞 (rascal/punk) - a self-aware label combining 'tasteful' with a hint of mocking 'punk'. Coined in Taiwan in the late 1980s and now used across Mandarin-speaking regions, often in the compound
雅痞族 (the yuppie tribe).
