he called me chubby. is it wrong that im upset?

okay before I write anything else, I know I brought this upon myself lol. but I was joking around saying how I ate my food really fast because I was super hungry, and because I'm fat. obviously joking, because I know I'm not fat, but I'm definitely not skinny either. so he goes "you're not fat, you're just chubby. and you're my sexy little chubby bunny" which was kinda offensive, even though I know I literally brought it upon myself, but am I over reacting by being kind of upset? or do I have no room to be upset because I was the one who put myself down first? I'm just trying to figure out if I'm real sad, or PMS sad haha
