If you're actually not being ironic: yes. He's a character from How I Met Your Mother, and a big internet meme because he is a childish man[censored] who uses the word 'awesome' all the time, in other words who every person on 4-chan wish they were.
Girl gamers are a myth, therefore people are trying to find proof that this girl isn't a "real" gamer. Thus, they misinterpreted the way she was listing things she'd done.
Yeah, I figured, just couldn't see how they interpreted what she said. Still can't tbh.
As for this chick, I've seen her on those rather infantile 'hottest gamer chick" polls, but haven't seen any of her shows. Still, judging only by those 10 seconds of video I'm gonna go out on a limb and guess that she's weird and annoying. I don't even find her all that attractive either tbh, can't say I see what all the fuzz is about.
Of course, it's also entirely reasonable to assume she's probably just an aspiring presenter who took the first job she could get.
I'm gonna go out on a limb yet again and say that you're probably right.
