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.
A plastic Barcelona fan is someone is just supporting Barcelona because of their glory. They started supporting the club because of winning titles. Right now when Barcelona are at their lowest have the majority of their fans left because Barcelona is made of plastic. They are probably going to support PSG because of Messi
Common names of people who are plastic fans of this run down club are: Ahmad, Mehmed, Zhang and Stefan
When you are a supporter of villa but you don't dare get out the confines of your house to go to such a shit hole of a ground.
I see Lee's a villa supporter! Yes but he's an Aston villa plastic fan ! He won't venture from the confines of Fladbury to get mugged and watchtower lose!
Back in the eighties and nineties, the phrase plastic-fantastic was coined to describe a cheap item that more than often broke when you started using it because the early day plastic was so brittle.
"I don't need a real lover, my television is my plastic fantastic lover."

Is nothing but an electric sign"
