How do you feel of people that make fun of you?

I'm not upset about this because.... This kind of people just find defects that they have; for example there is this dude in my clroom that has a voice that sounds so girly and I never made fun of him but randomly he calls me gay for no reason I just ignore it because I'm 100% secure of my self but I made a good comeback :D I call him Tinky Winky XD!, How do you feel of people that make fun of you for no reason...?
