pronoun
Internet slang first-person pronoun used humorously or playfully, often in online forums and social media. Derived from 俺 (ore) with the honorific suffix 氏 (shi), creating a mock-formal tone.
俺氏、今日も仕事サボりました。
I (humorously) skipped work again today.
俺氏はそう思うんだが、みんなはどう?
That's what I think, but what about you guys?
