Non-Planner 

Noun. Used to describe an individual that lacks the consideration & common courtesy for others while scheduling an outing. In other words , the day of the event rolls around and you have no fucken clue what time or place. It's like being in the Twilight Zone! Totally in the dark and the non-planner decides to ask later that evening what you'd like to do that night. Rude as fuck!

What a tool! He's such a non-planner! It's like he flys by the seat of his pants. It is so fucken annoying! It would have been courteous for me to have known what was on the agenda that night. I have kids ya know!
