Often such women live their lives on social media or talking to strangers in the street, commenting on things they disapprove of, preaching unsolicited lessons.

(Also common: Fat Tina, Fat Jennifer, Fat Claire, etc.)
"I was hanging out at the mall when some Fat Karen came up to me and said I shouldn't be feeding my toddler McDonald's. She gonna try to make *ME* feel guilty, when she weighs 280 lbs because she was once a student athlete 3 decades ago?!"
