I doubt it would catch on because most fans would pull back from 'Your A Twat' territory meaning not many would join in. No-one wants that feeling of joining in the song and your voice is the only one can hear when the song has finished and you carried on, or that clap, or claps, that you either carried on when every one else has finished. Or you may have even made up a song that went dead, or a clap that was just ringing out loud by itself. If you stand there like a prized prick and just swing your hands together has hard as you can, looking like a stutterers version of the YMCA, and you're the only one doing it, you will feel like a right dick.
So, no, I don't think it'll catch on.

"So, Damon, wow, I see you have your Thunderclap hat with amusing fake arms and a string to pull them together on, ha ha ha, You must be proud as an Aston Villa fan yourself that you are witnessing such a spectacle..."
