I usually get Nige or Nigey.
Nige is pretty obvious, it's just the ever so slightly shorter form of my real name - Nigel. Funny story about that is my parents decided on that name because they didn't think (or realise) it could be shortened to Nige whereas the other options they had all could.
Nigey was coined by a pal o' mine in Year 9 in high school. He was just like "Nigeyyy" one day at schol and I kinda liked it because it was fresh and new and it stuck for a while, too long actually. I hate it now to be honest which is why it lowkey bugs me when people say it, and in this age when you tell people you hate something, they intentionally say or do even more to piss you right off.
