My crush told me i look innocent, what does it mean, is there a meaning behind it?

My crush told me i look innocent he says I'm cute but one time he heard I was going to the mall with my friend she made a comment "we are gonna look for cute guys" he kind of looked mad and then look at me and smiled. Then at the mall he texted me saying "you looked sexy as fuck." Does sexy, hot, innocent, and cute has a meaning or just words? What does those words mean?
