The term 'vector' has multiple meanings across different disciplines. In biology, a vector can be an organism, like a mosquito, that transmits a disease - causing agent from one host to another. In graphic design, vectors are used to create images that can be scaled without losing quality. Since we don't know exactly which 'vector' the 'full story' is about, it's difficult to give a comprehensive account. But these are some of the common interpretations of the word.
It might refer to a vector image of exaggerated or humorous lips. Usually, these vectors have bold lines and bright colors for a visually striking effect.
I'm not sure specifically which 'vector 2' you are referring to. It could be a product, a concept in mathematics or physics, or something else. More context is needed to tell the full story.
