Nicking Around is the act of when someone is being really nice and gives you the idea that that they want to be around you. Then out of nowhere ignores and avoids talking to you or being around you in anyway. Nicking around is a random occurance, but when it does occur causes people to feel "nicked off".
Me: I asked David if he wanted to hang out today.
Beth: oh yeah? what did he say?
Me: Well it was good at first, but then he started nicking around on me!
Beth: ugh! That's so annoying, did you feel "nicked off" after?
Nickie is usually the best person you will ever meet. Innocent and charming, they will become very good friends, albeit socially inactive at times. Typically playing WoW or other games, a Nickie can be found bringing joy to other's lives often at the expense of their own.
Nickie is my best friend and one of the nicest people that this cruelworld can produce.
