Any action between two male friends that is not good bro etiquette. These actions can include, but are not limited to, cock blocking, flirting with another's ex girlfriend, and being a poor wing man.
Travis: Did you see what happened to me at the bar last night when I was flirting with Ashley?

Andy: Yeah, P-Money came up and bought her a drink and went home with her. That was piss poor brotiquette!
