the promise you make to someone who you really don't want to talk to you. usually because you have to do something important or you just really don't like that person. after making this "promise", you some how get tangled up in something more important or you "have" to leave right then. this is a perfect example of a "white lie".
ex. "Just a second, I have to do this first, be right back."
"I just dropped a fat bullshit promise on Karen."
