Leo

An absolute menace to society. Anyone who's named Leo will usually be very blunt about their personality and feelings towards others, and is not afraid of causing beef. In fact, they will often try to instigate arguments to show hostility, and gain personal satisfaction from it.

McDonald's worker 2: You mean pulling a Leo?! Yeah, I am. This guy is gonna have a McCum instead!
