As a sufferer of the square butt syndrome, I can tell you it would be more suited to a manga or anime than a regular cartoon
. Lots of angst and trauma and drama involved.
It is true, not an urban myth. I have ALWAYS had a high, tight butt, no matter how big I have gotten. But when I do the FL Firms, I do get the square butt effect and until you see it you wonder how that fleshy part can square off, but I can guarantee you it does. I had never heard of it until I attained it and then I read about it on here. I had already stopped doing the Firm with the FL just because it was time to move on. But it took a lot of time for it to go away. I kind of just ignored the glutes for a while hoping benign neglect would make them go away. It is really a flattening of the butt, if that helps you visualize it, as much as anything else.
Now that I know what causes them, I tend to just use the FL to hold my handweights.
