Just be yourself. Don't mind what others think about you! Thats your problem right there, just don't give a fuck what others think about you

And when they are speaking to another guy, just open the GUY first and if he ignores you and speaks to the HB even if you are trying to start a conversation with him, it makes him AFC chump.
You could open the guy with something like: "Whoa! Where did you get that shirt from?" -Blablabla answer "Thats cool, you have your own style. How much did it cost?"
Just chat the guy up, and if the HB tries to catch the attention just neg her. There you go

you got the idea I think. Also remember to change the frame so you can chat the HB up too, that way you have just changed roles with the guy next to you. Hes out, you are in!
