I freaking hate younger girls! ARRRG!?

I remember last year in Intro to Business cl, Jeremy and I were among the four only sophmores. There's these two freshmen girls, who all the guys dig, you flirt on me constantly, staring and laughing. They always talk about how funny my jokes are, and say my name in that strange amorous tone. But their way ontop my league. Preps, too. Lots of people who know them better than me say they don't really like me. Even the teacher says I should freaking "Go to their in-ground pool during the summer time for a HOT swim!" I usually respond by saying, don't start it, and the same one (Candace) always chuckles and says "He hates me." I'm pretty sure they're just f@$king with me. But I would like all this to stop. Every time I say they're just toying with my emotions or something, they deny it. Other people in the cl think I like her, and coax me to ask her. I don't. They act like s. I like finer girls. Anything I can say to get them off of me? 10 pts for best answer!
