I went with arm barbarian. Even though he takes a ton of heat from people calling him a "like whore", I will say that those gifs can totally make my day. And I am not alone. How the hell do you think the guy gets likes? There is a reason why the DC thread has 2.6 million views. The majority of people come on here to talk about MMA, read someone's insight, hear some rumors, or whatnot. And if you can get a good laugh while doing so, that is just gravy.
Aside from all that, he is a pretty regular guy type poster.
