Auburn fans have OGS (Online Gamer Syndrome).
Online Gamer Syndrome - though by no means unique to online gaming, and has been around much longer than the internet, it became widely understood by the populace at large thanks to the sudden increase in the online gaming community.
It is a mental condition brought on by taking humiliation after humiliation, where the only explanation the sufferer's condition will allow becomes their focal point - that the individual or team that is routinely dominating you is "cheating". The initial cause is unknown, but typically comes from a fan or player who feels that the only way that they can subconsciously justify the loss is to assume that the other player or team is acting in a manner considered "unfair".
Other possible reasons for the loss, including, but not limited to:
Being physically / mentally superior
Being better trained
Having a better strategy
Being lucky
Also note that this condition will cause fans or players to find their own team's "cheating" to be considered acceptable, with the caveat that "the other team/player" does it. Proof of cheating is irrelevant, and being found guilty through due process is not needed (and indeed, being found innocent is usually considered "proof" that said team has the powers that be in their back pocket).
