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.

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