I can't think of a nice way to say this, but people are allowed to like shitty things, and are especially allowed to like things even if the majority doesn't. Hell, she can even think the video was great and that we're all retarded, and that's OK, if she's happy about it, she should be happy, what anyone else thinks really shouldn't matter.
She's full of terrible taste that she can only explain in ways that make people disagree with her even more, but it's her taste in the end. I'm still going to fold my brain trying to understand it and then post about it on an internet forum.
