noun
Derogatory term for someone from the countryside, implying unsophisticated or rustic manners. Often used jokingly or insultingly.
彼は東京に出てきたばかりの田舎っぺだ。
He's a country bumpkin who just came to Tokyo.
田舎っぺ扱いされて腹
I got angry being treated like a hick.
田舎者 is a more neutral term for a person from the countryside, while 田舎っぺ is explicitly derogatory and slangy.
Derived from 田舎 (いなか, countryside) with the suffix っぺ, a colloquial and often pejorative ending. The exact origin of っぺ is uncertain, but it may be related to dialectal or slang suffixes used to create derogatory person nouns.
