attractive and expensive 优雅豪华的；富丽堂皇的 - (British English, sometimes disapproving)
typical of or used by people who belong to a high social class 上流社会的；上等人的
Word Originearly 20th cent.: perhaps from slang posh, denoting a dandy. There is no evidence to support the folk etymology that posh is formed from the initials of port out starboard home (referring to the more comfortable accommodation, out of the heat of the sun, on ships between England and India).
