I have many examples, as I spent a lot of years obese.
Some examples are:
my sister (with whom I’m now NC) spending an entire summer refusing to use my name and instead calling me ‘porky’. She was an adult, home from uni for the summer, I was an 11 year old child.
a primary school teacher, who was calling each child individually up to her desk and handing us our school photos, looking at mine and laughing, in front of the whole class
a man making ‘wide load, reversing’ beeping noises as I went past
a man jeering ‘here’s our biggest supporter’ as I went into a football stadium
a man who ran up behind me, grabbed my hips, then held out his arms, my hip-width apart and said something along the lines of ‘Jesus Christ look how wide she is’ to his friends, who all jeered
a man who commented on me drinking Diet Coke, telling me that the diet ship had sailed. I drink Diet Coke because I like the taste of it, not because of the calorie content.
a man who, the morning after a one night stand, told me he wouldn’t be seeing me again because he didn’t like fucking elephants. He looked a bit confused when I asked him if he was using fucking as a verb or an adjective.
that’s a brief sample, I could describe hundreds more.
i have since lost weight and am no longer obese, or overweight. All the people in my examples above are undoubtedly still assholes though, who are so pathetic that they feel good by taking time out of their day to mock a stranger. It’s a sad life, tbh.
