Ur fat is used by a child when all hope is lost. When they can't think of an insult so they say ur fat. I told this to my dad I now don't have an eye. But when you are losing hit them with an ' ur fat ' and watch them laugh at you. *Please note children if you say this to your teacher that's a woman they will take it personally.

Friend: Ur fairy bread without hundreds&thousands

You: 'can no longer win' " Ur fat"
Friend: Thats a trash insult loser hahahaha
You: god dang
