can someone explain this avatar for me?

[Alobar]

a ton of people have this avatar, or one very similar, what the [censored] is it? By and large most of them are pretty bad, usually over aggro, its to the point where even if I've never seen them play if they have this avatar I assume they are a tard until shown otherwise. I'd love to know what it is and where its from tho, can anyone help??
