A bullying tactic, singling out, or making fun of a fat person, under the guise of helping them realise they need to lose 50 pounds pronto or they're going to become ill, die prematurely, or be a major burden on the health system, when in actual fact it's an individual's bias against people they consider to be unattractive in their immediate social or professional circle.
1.You're a plus size female out dancing at a club with friends. You notice a small group of guys at the bar staring at you and laughing. Eventually one of them comes over and starts trying to dance behind you, rubbing against your ass, while his friends laugh uncontrollably. When you turn around and tell him to piss off, he laughs in your face and says, “Nah, girl, I’d totally fuck you if I thought I could find your pussy in all that blubber!”
2. You're a fat person using the elliptical trainer at the gym. A man walks by and gives you an encouraging pat on the shoulder. “GOOD FOR YOU!” he says loudly, a little patronizingly. He has pointed out that seeing people who look like you exercising in public is a strange and unfamiliar occurrance, an idea rooted in the assumption that fat people are uniformly lazy and unhealthy, and you, as an exception, therefore deserve to be recognized and lauded. You feel singled out, othered, and very uncomfortable.
3. A fat guy in a cafeteria is loading his plate with vegetables. The chef gives him a smile, makes a fat shaming comment, "I spose all that green stuff means room for more pudding eh?" as he sniggers expecting him to enjoy the joke that is essentially on him.
The fat guy finishes his meal and goes to leave the cafeteria. Just then a work colleague passes and grabs his male breast. "Caw get a load of these moobs! You lactatin' or what son?" jests the work colleague with a gaggle of sycophant friends with a collective IQ of 81.
