Question: Equivalent for extreme contempt/hate?

Kinamumuhian kita is correct If you just want to express that you don’t like someone you can use “Ayaw” .I HATE YOU - Kinamumuhian kita!I dislike you- Ayaw ko sa’yo (Ayoko sa’yo)

"Kinamumuhian kita" hits the nail on the head. This is the exact word I thought of upon reading the title of your post without even reading the details yet.

Another translation could be: Kinapopootan kita or Napopoot ako sa iyo.

Suklam is also an option

Magandang araw po sa inyo! I hope you’re safe in the middle of everything.I concur with PinoyTaj‘s response here. The Tagalog word for “hatred” is “poot,” while “muhi” is a sort-of incredibly intense “poot.” So yes, if you indeed just want to tell a person matter-of-factually that you hate them, you can say “pinopoot kita” or “kinamumuhian kita.”Unfortunately, I haven’t gotten into the Star Wars series myself yet, so I’m not familiar with the scene that you’re describing; however, if it’s anything similar to when people would yell “I hate you!” to someone whom they are incredibly angry or frustrated with (spur-of-the-moment like), there are better and more natural ways to convey this in Tagalog. There are a multitude of constructions for this, of course, but I would suggest “Umalis ka!” (lit. “Leave!” or “Go away!”) or “Ayaw kitang makita!” (lit. “I don’t want to see you!”).I’m sure others here have other suggestions as well.

@AngTaongsiClyde It's the kind of "I HATE YOU" where you seriously want them dead. So "Umalis ka!" or "Ayaw kitang makita!" just won't cut it. (You should tots watch Star Wars!)
