What does Lolita mean?

I was walking in school today from my locker and I saw this new teacher who is about 40 ish maybe watching me , who was admittly pretty cute so i smiled and winked, he and winked back.I have a boyfriend who is captain of the football team and im head cheerleader , but that doesnt mean I cant flirt and I would never cheat ever! I didnt expect him to wink back so I giggled quietly then kept walking , met my boyfriend and gave him a kiss and started just ya'no just teasing. Then the bell went for my next class which was english. My english teacher Mr.Harrison stops me on my way into class and says " Your very promiscious for a 16 year old . I saw you earlyer in the hall winking at Mr.Montgomery and i find your Lolita behaviour a tad innapropriate and this is my last warning.( he has told me off for "flirting innapropriatly" before . I know what promiscious mean but Im sure as to what Lolita means???
