[A nightmare before christmas] Why did Ooogie Boogie hate Jack and Santa?

In the movie, we're never really given context as to why Oogie hates Jack and Sandy Clawz, though it is made clear from how Jack talks about him when asking the three to not bring him that they have a history. In the movie, it almost just seems like they dropped santa off at Oogie's house and he was just like, "Well...I guess I'm doing this now"

Oggie Boogie, the notorious Bogeyman is a remnant of a holiday called Bug Day or Crawloween but this had been forgotten in the human world and he was forced to take refuge in the world of Halloweentown after his native Bug Town was destroyed.

In the Game Boy Advance game *The Pumpkin King*, he had attempted to hijack Jack's role as the Town's King and failed miserably only a year before the events of the film.

Edit: Also, the reason the townsfolk of Halloweentown hate him so much is because while they love to scare humans and get a fright out of them, they are not malicious and see everything as a fun joke. Boogie is expressly violent and malicious, often described as causing physical harm to those who he targets. He's also a notorious cheat who often gambles in deadly games to get people killed - his first boss fight in Kingdom Hearts is in his main lair and has him trying to use a rigged dice game/roulette table to kill Sora and his friends.
