Your reply. It confuses me. Was that supposed to be a link or something?
Apparently that's not how the internet works anymore, people just pretend to make links because it gets roughly the same idea across. It's like, "let's all agree that I found a video of Big Mac saying nope and posted the link here."
Linguistic innovation. The internet has it.
Actually, nope.avi references a specific video on Youtube (and possibly elsewhere) where some character from TF2 runs up to the camera, says "nope", has his neck grow in length, and then runs off. It's a meme cited under various circumstances (I don't know what specific cirumstances, if any, it tends to be referenced in response to), but is especially relevant here (because of the similar weird neck phenomenon).
I'd find and link the video, but I'm on a phone that's a few IQ points shy of being a smart phone. No Youtube for this yoshi at the moment...
