When you can not be bothered talking to someone on Facebook chat anymore, so you go offline. Later when talking to that person you blame it on Facebook "stuffing up"
Mike: Hey man, why did you go offline before?

Dan: ahh sorry mate, facebook was stuffing up

Mike: you were pulling a Slackchat wernt you ><

Mike: sorry :(

Get the slackchat mug.
When two peoples' snapchatting frequency slowly decreases when the novelty starts to wear off.
We used to snapchat each other for hours on end but we haven't sent any in a few days. We've been slackchatting!
