13/19. I thought I'd do better at this!

Too bad some pictures are really low res, but it's otherwise an interesting kind of test.

This test is shit because both men an women can do squats or have implants to have equal-looking asses

That was suck! I'm a half-ass, that was test has all dude ass everything. Not a single women ass don't shape like a box.

15/19 smart ass! Lol
