No one fucking teach you to make fun of others retard, only insecure people have to mock others to satiate their own desire for superiority, if you're truly confident and successful then your ego can stem from your achievements. In this case, how does fucking mocking someone's appearance, something they can't necessarily control, boost your own self confidence, are you going to take pride in looking better than someone? How fucking superficial can you get? Fucking achieve something in life instead of going around mocking physical features.
Flag checks out tho you're probably obese and trying to mask your insecurity
