Barry-Out 

To end a night early for a very poor reason, e.g. tiredness.

To agree to do something in advance only to later cancel with a poor excuse.

'Dave really barry'd-out just as the night was getting started'

'I see Mike has barry'd-out of the night again with one of his usual bad excuses'

'It would be nice to go out this weekend and have nobody barry-out on us'

'Why are certain individuals always barrying out on us?'

Black out Berry 

When a person is so obsessed with his blackberry that he totally forgets where he's at and what he was doing.

He: HUH?! Where are we?
You: Dude we just went to the super market!

He: I can't remember!
You: Put that thing away!!! you're suffering a black out berry!
