Okay so I'm pretty cool with this one guy but every time we speak in front of other peers he says "hrm0894 fuck you" and flicks me off. I really don't know why he does it, presumably to look cool in front of others. Before I discovered this sub reddit I would just ignore him. Now I want to know how an Alpha would deal with this situation and how an Alpha would command respect.

Edit: oh yeah I forgot to mention that were both in college and in our 20s. The guy just acts like a kid lol.
