WAS SHE CALLING ME FAT??

I'm a 15 yr old girl, and today in school there was an incident..... While walking in the hallway, I abruptly cut across the path of a few girls, because I was walking to the bathroom. One of them shouted, "HEY, NEXT TIME PUT YOUR GOD DAMN BLINKER ON!" I'm just wondering if she was calling me fat, because maybe she was comparing me to a car....please help!!
