I like the Terrible Towel as an icon because it works on at least 3 levels

1. As a towel it is just terrible
2. it’s just the most annoying thing if you aren’t a Steeler fan
3. GO STEELERS WOO FEAR THE TERRIBLE TOWEL SIXBURGH PEROGIES PASS ME THAT KEG OF IRON CITY

As a fan gimmick it’s probably the best in the NFL. It’s very simple, it’s iconic, and it’s absolutely annoying as shit for ever other fanbase. It’s very, very Pittsburgh and very very Steelers. I may hate it and think it’s a stupid ugly gimmick rag, but I respect it.
