A term derived from the infamous bail brothers, Seacan and Deacon Bail. Used to describe one or more of your family, friends, etc. that constantly makes plans to do something and then decide to bail on them at the last minute (sometimes without even letting you know they aren't going at all).
Wow, I guess Daneal didn't feel like coming today. What a sleasy bail brother
