TV ad? Or just an Internet meme?

I've heard something about "My Pokémon bring all nerds to the yard" and "I trade you but not Charizard" or something like that...

What is it?

My pokemon bring all the nerds to the yard,
And they're like "you wanna trade cards?"
"Damn right, I wanna trade cards,
I'll trade you this, but not my Charizard."

I've seen it in someone's signature on this very forum, but I'm not sure where it originated.

It may be an internet meme, I'm not sure
but the gif came from here and there's also a version of the song sang with those lyrics
It may be a ytmnd thing
