To steal one small, not very valuable (in terms of money) thing out of a whole bunch of the things in a very 'sneaky'(ish) way, and then do it again and again from different bunches of things that belong to different people or groups because they won't notice if one of the things is gone and it won't really impact them in any way. Like going on a walk and stealing one flower from each yard to make a bouquet instead of stealing a bunch of flowers form one yard because no one will notice if one flower is gone and it makes you feel mischievous and sneaky in a delightful kind of way.

"I went pit-nicking for a bouquet of flowers." "I pit-nicked some candy from the pantry while I was at my best friend's house."
"I've enjoyed a bit of pit-nicking in my life. I love stealing flowers from other people's gardens." - Aurora Aksnes
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 soannoying, did you feel "nicked off" after?
When one has a sudden head rush due to rapid nicotineingestion. It's common to see in people who have recently started smoking or someone who is vaping at a particularly high level of nicotine.
