My sister is a fucking ham who thinshames me I'm staying with my family for winter break until class begins again in January. I came home to find that my little sister has transformed into a Class I planetoid. She is 5'4" and well over 180 pounds, with gigantic flabby thighs, a huge butt and a proto-fupa. Her arms look like sacks of cottage cheese. She bent over once and her too-small shirt bunched up to reveal angry red stretch marks all over her muffin top. A few months ago she started rapidly putting on weight. Her boyfriend dumped her last month (probably because of her weight gain) and she has been ballooning ever since. She dyed her hair platinum blond, wears a shit-ton of makeup to hide her greasy face, and got a nose ring for some reason. She looks like a Jynx pokemon crossed with a trashy hipster. She has been really aggressive around me ever since she started to gain weight. Like shoving me, insulting me and generally being a brat. She was almost done eating an entire bag of potato skins when I confronted her about her weight. "You just had a huge brunch. Stop stuffing yourself with junk. You know you are obese, and I'm just trying to point you in the right direction." I'd seen it with my own eyes. She'd devoured two pieces of my homemade Christmas lefse (Norwegian potato pancake made with flour and cream) stuffed with an entire bowl of chestnut stuffing smothered with gravy, like some kind of horrible burrito. She started screaming at me about the usual fatlogic bullshit. "BMI is garbage because my friends said so. I'm not fat, I'm healthy because I'm normal. I'm just big because of my genetics. I don't have time to exercise. I'm not naturally athletic like you. I'm always hungry because my body says so! I'm practicing intuitive eating because it's natural. I get enough exercise with my cashier job. I just really need to love my body now, okay?! I don't care if I'll live ten years less, I just want to eat what I want." I tried to explain to her that the human body is only supposed to carry so much weight, and that being obese put her in danger of heart disease and joint degradation. In ten or so years, she will have to deal with a shitstorm of miserable diseases. It doesn't matter that she feels "healthy" now. The ham wouldn't have any of this. She launched into an angry tirade. "You shouldn't be criticizing me. You're an anorexic skeleton and everyone knows. You don't eat enough. You'll never be able to have kids because you don't weigh enough and you don't have any body fat. My body is made to make babies. You overexercise and you look like shit. Humans aren't supposed to run marathons." Somehow I'm a malnourished skeleton and capable of running marathons. K.  But that wasn't all.  "You're just jealous because I'm curvy and beautiful. Boys tell me all the time that I'm pretty. They want me more than you! That's why you're a lesbian, because you're such an ugly skeleton that no man will ever want you!" Even though I've heard this shit a million times from angry sows on Reddit and Tumblr, it kind of hurt because it was coming directly from my sister. I have no idea what has gotten into her. We used to shitlord together and make fun of hams all the time until recently. It's like she was assimilated by the Borg. It's painful to watch. I'm close to strapping her to a bed and beating her with a cross until the HAES demon leaves. Less than an hour later, she was stuffing herself with a basket of onion rings and a huge pumpkin milkshake, making eye contact and chewing angrily like this to establish hammy dominance or something. It was at that point that I knew that she had joined the fats and was no longer human.
