Most women would be turned off and maybe find it even creepy or weird that a guy that had just asked her out for coffee sent her a rhyme or "cute" little message out of the blue. If that is beyond your understanding then I feel bad for you because it isn't really that hard to understand. It has nothing to do with putting girls into categories or how many types of girls there are in the world. I would continue to explain to you why sending a "cute" text with a silly rhyme is a bad move but it is clear you don't get it and won't get it so carry on and due something of the sort to the next girl you ask out and barely know. Be sure to check back in and let us know how that goes.
