Pre-Bail Bail 

When you know someone is about to end a conversation, so you end it before they can.

I was talking to Brandy and could tell she was going to cut me off so i used the pre-bail bail.

pre bail 

To set up an escape route for an upcoming event or function that you're not sure if you'd like to attend, but don't want to rule out completely.

I had to pre bail on my grandma's birthday party and told my mom I had a headache in case I can score a ticket to see Death Cab.

Pre-bail

To drink so hard during the pre-gaming session you can't make it to the club.

Sorry Trista, I need to pre-bail on going out tonight because I drank to much.
