“The moral implications aside, the better reason to stop using “fratty” is that it stands for so many things that it ends up standing for nothing. Which means that if you use “fratty” when you really mean “homoerotic,” you’re either lazy, stupid, or hungry for vengeance against the guy who kicked you out of that smoker party your freshman year.” – “If Everything is Fratty, Then Nothing Is“; Mike Riggs, Village Voice

All prejudices aside, Riggs is arguing here for better writing and that’s reason enough.
