>always think she has a model-esque figure
>tall, skinny, thigh gap, small tiddies
>"hey that's kinda cool my gf looks like a model"
>actually look up her weight on a BMI calculator
>168 cm tall, 38kg => BMI of 13.5
>look up pictures of people with that BMI, they're all severely anorexic
>internet people say that having a bmi under 14 is life threatening
