Japanese DictionaryDefinition of ひとのうわさもしちじゅうごにち
- (exp) wonder lasts but nine days; gossip lasts just one season (lit: 75 days)
そんな失敗なんて気にするな。人の噂も七十五日。みんなすぐに忘れるさ。
I wouldn't let a goof-up like that get to you. People have short memories and the one good thing about gossip is that it's short-lived.
