If Magic world got a spell with "[Counter] Destroy target Ninja" that's a hate card. It is only useful when fighting Ninjas. This card likewise has an ability that is highly useful against one subset of cards, and meaningless against any other. That is the definition of hate card. It's a card that "hates" on a specific play style or group of cards.

If you don't understand this I don't know what else to say as that is barest bones defenition of hate cards I can think of: A card that is highly effective against a certain playstyle or group of cards and useless elsewhere. Gumi slime is another example: Meaningless if your opponent doesn't have move monsters but very useful against those that rely on it (Like weapon dependant worlds)
