Plastic Fan

Someone who whores their allegiance out to multiple different sports teams from the same sport. While some only support two clubs in the same sport, there are fans out there who produce enough plastic to wipe out the entire turtle population with their outrageous team body count.

I have this friend who isn't even from England but he still follows the premier league. He's such a plastic fan, he goes for Brentford and Chelsea, despite the fact that they are both in West London and will be rivals after Chelsea becomes a small club when their Russian sugar daddy leaves them.
