What does it mean when a straight girl calls another girl 'cute'?

So, I was a student at this rural one-year boarding uni prep school, I am a female but unfortunately am unlearned in many of their ways (take pity on me 'o reader.) This year I was greatly confused, all the girls often described me as 'cute', 'adorable' and other such adjectives. I'm taller then all of them, they're all straight (to my knowledge), I'm in no way inferior or behind them in grades, fitness, ability or age (I was the eldest girl there by a few months.) So I'm confused, what does them calling me 'cute' or 'adorable' mean?
