"Big pig's hoof" means that "a man has no good thing", which is a common term used by girls to diss boys to change their minds and break their promises. It can also be used to spit out boys who don't understand amorous feelings and are straight. It means philandering everywhere, which originated from An Lushan's nickname Dragon Pig. Because An Lushan was having an affair with Yang Guifei, she scratched Yang Guifei's chest with her hand, so the pig's hand also extended to lust and promiscuity. This pig hand is also the source of salted pig hand.
