No. They're calling it that because of that video. It became an epic own as soon as he posted it.

And it was. He unironically went on this long winding diatribe about her penis size being advertised by her email address which he unironically thought was real.

I don't know, maybe he was drunk and/or on drugs but that video and how he worded his little fragile man diatribe is what made her tweet an epic own.

Once again, everyone seems to be able to suss all this out easily enough without a field guide except for rape and misogyny apologists.
