Imo, "cute" means that you have an adorable & youthful look & demeanor to you. Since you're referred to as "super cute"...that is you, but multiplied. :)
Personally I tend to go for "cute" girls more than "hot"/"sexy" girls. Just my preference. I find the demeanor of a "cute", or "super cute" girl, more attractive than a smok'n hot girl portraying sexual confidence.
The word "pretty" imo refers to an attractive face, whether the girl is mainly considered "cute" or "hot".
cute means atractive in a non-sexual way, hot is usually sexual attraction. you can be hot and cute most guys don't use the two terms together. super cute is more then cute. it means exactly what you would think it means.it can also be personalty. like to me when a girl gets nervous and akward its super cute
