Make some fat insults
1. You're so fat, when you wear a yellow raincoat, people yell "Taxi!"
2. Your belt is like a front bumper on a Cadillac.
3. Are you made of queso? Because you're so cheesy and fat.
4. I'm not saying you're fat, but I am saying you aren't a shining example of self-restraint and healthy living.
5. You're so fat, you don't have to worry about getting a tan – you've got enough shade for everyone.
