It's just an archetype. A skeletal frame that gives an idea of a character's personality. When Touka for instance is called a tsundere, it's just supposed to get across the idea that she's a person who's rough around the edges, but ultimately a good person.

It's like calling Kaneki a "bookworm". Without knowing about him, the idea of a nerdy and intelligent but possibly socially awkward person comes to mind.
