This is definitely really hurtful when it happens in reality, but I find it the idea of it pretty damn hilarious. It's really just a euphemism for, "Wow, you're fat. You're not pregnant are you? Because if you are, your massive gut might be mildly acceptable. Otherwise, you should probably consider laying off those Baconators and hopping on a treadmill once in awhile, you giant hippopotamus."
