I voted this up in the hopper just on this fact. I'm pretty sure I've met at least one twelve year old girl who weighs that much, and Jesus Christ, she still didn't look like that.
I felt personally offended by that because when I was an (albeit tall) 12-year-old-girl I was at least 120 pounds, and I was still a skinny little shit.
She'd have to be like 3 or 4 feet tall to look like that at 120 pounds. You think someone who obsesses over this to the point of making the video would know what 120 pounds actually looks like.
