We get called LSWho? a lot.
Always struck me as a bit unoriginal and needlessly generic. You could insert Who? for almost every university, many of which have a "U" in their initials. That's the biggest sign of disrespect, when people won't even take the trouble to come up with a decent insult for you.
Like corndogs. A) That's a Colorado jab hurled at Nebraska (Cornhuskers....makes much more sense) that was lazily co-opted by an Auburn fan one day and directed at us. B) Corndogs are delicious, so it's not much of an insult.
People ask me why I hate Auburn so much. That's one of many reasons.
