A nickname usually originates from someone's real name. These are usually used to make names shorter and thus easier to say. But like everybody else, I have a couple of nicknames, and some of them are not related to my real name, Netherlen.
Naknak - from the word "anak", mostly used by family members, relatives and friends from elementary
Naksi - it's from Naknak but with style
Ging2 - I really don't know why i had this nickname when i was a kid, it didnt last that long though
Nedeth - I used this when I was in high school. It reminds me of the so silent, obedient, righteous girl :)
Nedz - this is my official nickname. I started using this in college. I find it cool. Just read it with an "s" you dont have to buzz it, but please don't spell it like Neds, so baduy :)
Nedzy - this isn't official, but some of my friends from eTel use this
