Ur Mum

Ur Mum is a person that is usually really hot or really fat ( in American jokes ) spelling it in an American way ( Ur MOM ) is unacceptable.

Ur mum

The comeback of all comebacks. Used for the ultimate destruction of your friends when you have nothing else to say.
Also used for referring to Morgz Mum (aka. The Bill Gill) who is too amazing for this world but at the same time bald martin is better than her.
