Would this be too immature to do? Also, how do I get over what she said?

yes i see how you would be mad at this but i dont think that retaliating with a nasty song is the right way to go. i would either forget about it or confront her, in person not on facebook. Also, i dont know about you but where i live, for some reason people use the word gay to represent someone stupid, which is wrong i know but we do not mean that people who are gay are stupid, it is said like oh well she is gay, meaning stupid, so maybe that girl just meant something else by what she said. maybe ask her?
