What does hook mean in rap?

In rap, hook refers to the most attractive part of a song.

Hooks generally appear in chorus, but hooks are not chorus. Hook originally meant "hook" and extended to "attract people". A hook song is not necessarily a hook song. Hooking songs are just a form, not a system. Almost every song has a hook.

For example, the familiar chorus "We Are Young" can also be regarded as a hook, but no one calls "We Are Young" a hook song. Think about Hook's Chinese name: saliva song, not elegant.
