noun
person who asks others for answers without researching first
Internet slang for someone who posts questions expecting others to do the work, without making any effort themselves. Often used critically.
掲示板で「教えて君」がまた簡単な質問をしている。
On the forum, a 'teach-me' type is asking another simple question without looking it up first.
自分で調べずにすぐ聞く人は「教えて君」と呼ばれることがある。
People who ask right away without researching themselves are sometimes called 'oshiete-kun'.
Similar meaning but uses the suffix ちゃん, which can sound slightly more mocking or condescending.
From 教えて (oshiete, 'teach me') + 君 (kun, a familiar suffix for males). The suffix 君 here adds a slightly mocking tone, implying the person is like a child who needs to be taught.
