Well, Ive explained this before. Quirk is what I call what you call hax physics. I call it quirk because the first version to use it was 6.3, and it was captioned "quirk". Quirk physics are basically a slightly higher endurance. This doesn't mean the game is any easier, just produces different results. Basically, it is %2 harder to get bosh to crash. Here is a link to a video I just recently made/uploaded showing what it looks like.
