That's generally what most people mean when they say "no personality"
Anyways you're missing out girl, cuz pussy is the beeeest :D
I've always considered 'No Personality' to be someone who isn't inherently interesting or unique or lacking depth of character, be it in their behaviour, life experience, interpersonal skills or even hobbies.
That said, it's pretty subjective. I wouldn't exactly say a girl lacking in intelligence is inherently lacking in personality, in fact it could easily feed into the 'Lovable goof ball' type persona. In that instance, her lack of intelligence could be quite endearing. Intellect is a fickle subject matter since it's a wide spectrum, so I'm not sure if you're referring to knowledge base, social acumen, emotional sense, inherent wisdom or some other factor.
Likewise with being shallow, it can often be a strong trait for some people, so I can't say they don't have a personality when it'll likely be accompanied by other traits such as materialistic or deceitful, it's just an ugly personality, to me anyway.
