Butts can be ruder than people.

If you had your choice, would you rather have an ASS or a collections agency call you?

Some would say that they are both asses.

I'll leave that for you to judge.

I will say this, ass calling is actually a form of respect.

Ass calling proves that the caller has the callee in their phone, and has called them recently.

The callee should be happy that the caller didn't fart in their ear and say, "Can you hear me now?"
