There's a guy at my work who is basically reddit incarnate. He posts dumb screenshots from there all the time. He speaks in the cutesy, affected, self-important, yet sniveling way they always do. He's basically "kind stranger": the person. He produces close to nothing in terms of work. He gives unsolicited, nonsensical advice to people far more competent than him.

I'm tired of listening to his drivel, and I want to fuck with him. I need a way to do it which won't come off as hostile or aggressive. How do I irritate this redditard as much as he irritates me? We work remotely, so our interraction is all chat and zoom.
