It’s an interesting question and one that comes up all the time for people who talk sports a lot. When you meet someone new and find out thier team you sometimes question where the allegiance has come from. I know that when I’m telling someone who I cheer for I often feel the need to include the phrase, “I’ve always been a insert team fan” or tell them I’ve been a fan since whenever. Especially if my team is doing well. People are so quick to throw the bandwagoner term out there. To me it means when someone really shows no allegiance to any team and is always cheering for the winners no matter who they are.
I totally agree, I love all the Miami fans there all of a sudden were as soon as the Big 3 showed up, then all the Cleveland fans
