Man, remember the Dead or Alive fighting game, and it’s “jiggle physics?” It was titillating (which is a single entendre here, I think) for about five minutes when I was 15 or so, then I wanted to turn the damn effect off because it was just off-putting. As the Wife said of the anime we watched five minutes of (and then turned off because it was weird and kinda gross with the whole sexualized high school girls thing), boobs don’t bounce and jiggle like that every time a woman does anything.
Perhaps…perhaps anime isn’t the bastion of anatomy and physics we were led to believe?
