Somebody, almost always male, who is incredibly adorable, attractive and cool, or the ultimate of them all.
Usually someone famous, it applies to fictional characters too, eg. in books or films.
To refer to someone as your uber-hunk means "I think they're beyond cool, and if I had my way I would like to bed or marry them in the near future."
