Most Helpful Guy
Girls flirting with their eyes, just smiling and winking. When girls try and copy(mimic) boys that's funny too, and I'm not talking about that manly deep voice stuff, like just stealing your hat and rapping/singing along to a song the guy could like. For example the role that girl plays in Zombie Land if you've ever seen the movie, or this artist name Syd from Odd Future (you'll hear about them soon enough) she's very talented and isn't the typical female you'd see on the streets. (It's hard to explain her situation but she's does silly stuff all the time that's cute)
That's just my opinion.
