When a fan from an opposing team makes a grammar or spelling mistake during an argument on social media, readers automatically deem them "Classic Team X" fans.

Now, we have the data to prove whether poor grammar truly is typical of a particular fanbase.

A proofreading company named Grammarly took the time to research which fanbases make the most grammar-related mistakes. Grammarly analyzed 150 reader comments of at least 50 words on each team's website, looking for anything from spelling mistakes to punctuation errors.

Grammarly has turned all of that research into easy-to-read numbers to determine which fanbase has the worst grammar. It does not appear as though a team's success has any effect on how "smart" its fans are.

Let the bashing begin.
