The Sportsball Meme
The sportsball meme is the internet love letter to the casual fan: you do not need to know the rules, you do not need the score, you just need maximum enthusiasm for whatever ball-adjacent event is on TV. Go Sports! Move the thing to the other thing! That is sportsball—and this is our fan, fully worked up because his team did stuff.

The sportsball meme works anywhere people are pretending to follow the big game: the office pool thread, the family group chat, the watch-party invite. Drop in our fan in his yellow Sportsball sweatshirt, add Go Sports and move the thing to the other thing, and you have said everything worth saying about cheering loudly for a sport you cannot name.
This is our original illustration of the joke—free to download and share. Save the PNG, post it wherever the game is on, and when someone asks who is winning, just point at the thought bubble: my team did stuff.
