A person who displays erratic, unpredictable, socially awkward behavior. You know that guy that gets drunk and makes the whole crowd feel uncomfortable? You have no idea what he's gonna say, but you stick around because you're half curious, half mortified how people will react.

Inspired by Bizarro-superman's Bizarro-world, but spelled differently due to represent that special someone who is always operating in a different dimension.
A "Bizzaro" at the lunch table at his corporate job: "Hey do you know what the Japanese do with erections?"
Persons B,C,D: "..." (uncomfortable silence)
Bizzaro: "They vote, just like us!"
Person B: (looks down at his napkin)
Person C: (fidgets uncomfortably)
Person D: ".....OOH KAY...." (more uncomfortable silence)

Bizzaro Hunter 

Bizzaro Hunter is a member of MHX. He joined sometime around September of 2002, and has thrown in the towel several times before being outright removed. Bizzaro has bullshit his way through the ranks of MHX and is a Nightmare Reaver, in his wet dreams. He is Overlord of Graal Online, a game known to most as the most disgusting pile of dung held on the internet and seems to think people care. Bizzaro has hopes of some day becoming a Blood Reaver, and thusly a Phantom Reaver, though it will never happen because he's a narcissistic little douche. He loves himself, and would make up any excuse as to why someone should take a bullet for him. See also drama whore.
I respect Bizzaro Hunter, because I AM Bizzaro Hunter.
