Hang around a guy who exhibits any of these behaviors and chances are you’ll think to yourself, what a douche. You understand that these behaviors are annoying at best and toxic at worst, and that we should all work to understand and admit when we might be guilty of them. That’s how we keep ourselves in check; that’s how we become better friends, co-workers, and people in general. As knowing is half the battle, there’s worth in reading a recent reddit thread in which u/Pitiful_Airline1092 asked “Men of Reddit, what pisses you off about other men?” The original post garnered thousands of responses and the comments all speak to behaviors that have their roots in insecurity and general stubbornness. Here are some of the more popular responses, each of which received thousands of upvotes apiece. It’s plain to see why these answers were up-voted by so many users. Each refers to behaviors that, for reasons due to insecurity or — let’s face it — general assholery, seek to demean or belittle. Who among us hasn’t been in a situation where someone exhibits this behavior? But also, who among us hasn’t been guilty of some version of this, whether we realized it or not? It’s a good reminder to keep ourselves in check — and that, no, you’re not the only one who sounds the douchebag alarm when this behavior takes place.
