I'm going to sleep 

When the person you're talking to or texting really does NOT want to talk to or text you.
It has to be late at night, otherwise it would make no sense whatsoever.

John: What's up?
Victoria: Not much, I'm going to sleep.

I'm going to Joes 

A phrase used when your friends bail out , or do not want to associate with you. So instead you find some hell hole to go to and waste your time there instead. Also can be used when something your working on does not work out right. The word Joes comes after a run down shit hole bar in Reading Pa, that contains nothing but trash.

Lindsey: Can you pick me up tonight to go to the bar.
Mike: No!
Lindsey: Fine I'm going to joes.

Alex: I can't get the car started.
Travis: Is it a Dead Battery?
Alex: Yes, I'm going to joes.
