Me and this weirdo are making viral tree climbing videos.
I dunno, I probably shouldn't say that because now it's just self-promotion and I'm going to get snarked at, but screw you guys, I love my stuff.

a video by this guy was posted above, is there anyone who speaks French and can explain what his deal is?

Judging by his videos he seems like a mega-pretentious art critic wannabe. He's been getting trolled by a French video game forum for some time. Seriously, just check the comments on his Q&A video. There's remarks like "vous etes fermé, arrogant, et ignorant" and questions like "Aimes-tu l'anulingus ?" I don't think you need to be fluent in French to understand them.
