bailmail 

An email used to excuse oneself from a date, appointment, or other commitment.
This is usually sent to someone that is known to have a wireless email device and it is usually sent close to the last minute. Bailmail is most frequently sent from someone who has found something better to do.

Bailer: This party is amazing!
Bailer's Buddy: Hey, don't you have to get to that dance thing in a few minutes?
Bailer: Nope. As soon as I found out there were free drinks here, I fired off a bailmail. I'm set for the night.

bail-mail

An email or text message sent to excuse oneself from assisting in a project, thereby fucking over the person undertaking it. Film students are notorious for it.

Dude, I just got bail-mails from my entire camera and sound departments. How the fuck am I suppose to shoot my thesis film?
