This video will kill more brain cells than a bottle of cheap whiskey.

I almost want to feel that he's insincere about this when he brought up the "Full Metal Jacket" bit.

The only thing I think he's insincere about is his position on hentai, which he elaborates on in some of his other videos. Never trust an anime fan who says he doesn't watch hentai. NO anime fan is grossed out by hentai; the ones who say they are, are either liars, or so pathologically repressed that they likely keep a cabinet full of dead hooker bodyparts in their basement.

Hey man, I just don't like seeing my waifu in all those lewd positions with OTHER MEN, okay?

I see no value in hentai, I see plenty of value in the (admittedly SCARCE) pool of quality anime movies or series'.

People who like this garbage probably like Excel saga and other childish garbage. Hentai is pretty much completely non-sexual to me. Cannot get a boner from anime style art unless it's really well done and there's inflation fetishy themes. Even then, i'd choose a real artist over an anime doodler.

Besides, non-hentai anime is usually far more arousing than actual hentai. If I had to choose between jerking off to someone from Legend of the Overfiend or someone from a Type/Moon series, I'd pick the latter every time. Every single time.

You're creeped out by hentai?

And I found it while looking for videos about brony furries.

'brony furries' is worth a few stars.

So, was "I was arguing with a brony on the internet" in fact referring to Evilhomer!??

Oh, yes. Evilhomer and I have a very healthy relationship outside of this site, and we've had one for quite some time. I'm the posh tsundere in the relationship, and homer's the genki tomboy. Basically, I'm Stocking, and he's Panty. If you want to put it in MLP terms, I'm Octavia and evilhomer is Vinyl Scratch.

We make out all the time.

I haven't the slightest idea what any of that rubbish means, and I feel this is a good thing, but I am glad you two have found happiness together. Let a thousand flowers bloom.

Tsundere and genki are popular anime archetypes. Tsundere are outwardly cold bitches, who turn out to be warm and passionate on the inside. They're also sometimes found with a signature moe look; if you see a girl in a pleated skirt with thigh high socks (there's a specific ration of skin-to-to-stocking that I forget offhand), chances are she's a tsundere. Examples include Twilight Sparkle, Asuka from Evangelion, and for you non-cartoon watching cultural elitists, Mr Darcy from Pride & Prejudice. Genki tomboys are, unsurprisingly, tomboys! Feisty, energetic ones, to be exact. Examples include Rainbow Dash and Rebecca Chambers from Resident Evil.

Panty and Stocking are characters from the anime, Panty and Stocking with Garterbelt. I've actually never watched this anime myself, so I can't say much about it, but anyone who spends time in pony communities will recognize the series, as Stocking bears a striking resemblance to Twilight Sparkle. This fact led to all manner of conspiracy theories, especially during the run-up to Equestria Girls.

Finally, Octavia and Vinyl Scratch are two popular background ponies, a cellist and a DJ respectively. There is very little information about them in primary sources, but they've accumulated a wealth of established fanon, more-so than nearly any of the other "fan ponies" (Lyra, BonBon, Derpy, RoidRage/Snowflake, etc). They are especially popular with brony musicians - nearly every musician in the brony music community will make reference to one or the other at some point, often repeatedly, ad nauseam. Octavia is an uptight, cultured classical musician, while Vinyl Scratch is a cool dubstep DJ (going under the name DJ-Pon3). They are typically envisioned as roommates, frenemies, and sometimes lovers; usually all three.

So you two are sort of like The Odd Couple, but with additional cartoon horse vaginas. I got it now.

I'm always wondering if people like this are hoping to somehow become "leaders" in their fandoms or if this is just one of those bad ideas that doesn't stop them from hitting "upload."

If he doesn't care about the opinions of others, why make this video in the first place?

I think it's more wanting to talk than it is any awareness of oxymoronic statements. As far as being a "leader", yeah, I can see that if you're a socially isolated "prodigy" or frequently lauded as "bright" in school, but I think it's more "not understanding how an opinion works socially". It's a bit of being unaware of a power trip when you're used to speaking but not receiving feedback that isn't positive.
