Ur mom can be used as the last line of defense when you are on the losing end of an argument. Scientists have proven that 90% of the time Ur mom can be an effective comeback to almost all sorts of arguments. But be cautious when it comes to the person you use it against. For instance, if you use this to ur mom, the next thing you know, you are homeless and instantly disowned. And if you use it against your dad then I'm afraid that you are now fatherless. He probably went to buy milk.
