How to tell a girl she's fat

Well there are a lot of ways to tell a girl she's fat but it depends how suicidal you are.

So if you have a lot of balls .... you should probably visit a doctor,it's not ok to have more than two balls.But if you have a lot of courage you can just tell her she's fat.

If you go with her at shopping you can tell her:"If I where you I would go on XL".Only If you mange to survive the shopping,because I went once shopping with a girl and I'm never going to do that mistake again.NEVER.

If you take her out at a restaurant:"You should try the vegetables ,you know,low fat and that kind of stuff."But tell her before the waiter puts the tableware,you don't want to get stabbed with a fork or spoon.

If you visit her house:"Isn't that couch a bit to small for you?Anyway the door sure is.Have you ever though of going to the gym?"

Or "I'm sure you like singing",but maybe she won't get it.
