A phrase that girls use, mainly when talking to other girl friends. It's primary use is for when you are asking to be updated on the progress or plans of a situation. And girls use it. Just girls. Mostly girls are the user of this phrase. Girls. Eric? No. Girls. Not Angie though. She's not THAT much of an annoying girl.
With that definition in mind.... (hence):
-- "Okay, let's figure out these plans for sushi and the mall this week."
-- "Alright... keep me posted! :)"
