hatter 

A male or female who supports the mighty Stockport County FC. Often confused with fans of Luton Town, who are also known as Hatters, but as Stockport were formed first (1883 to Luton's 1885) they can lay claim to being the original (although certainly not best on recent performance) hatters. Also occasionally confused with a character from Alice in Wonderland.

Hatters are generally discontented with life due to the direct correlation between perfomance of football team and general happiness.

Wow, how is there any reason that he dislikes Burnley, Man City and Manyoo?

Yeah, he's a Hatter.

hatter defense

A defense to trolling, most commonly on World of Warcraft forums, that involves saying that the troll "can't stop hiding behind alts and troll on their main." Usually improperly punctuated with poor grammar.

Near perfect execution of the hatter defense:

"Is it because I have what little balls it takes to post on my main, I mean I understand the point of some trolls its either they want some anonymity, which makes no sense seeing how your in a faceless game, or they want to make you mad because you don't know their main and can't bug them"
