last name your family’s name
first name is the name your parents gave you
nickname is one you give to you, it’s like a tattoo, if you haven’t got one already think about chosing one.
For nicknames I think best nicknames has these characteristics:
- shouldn’t be too long
- it should be meaningful to you
- you should use them in all of your accounts/services you register on, so others can identify/find you everytime, everywhere with only that string. yea, consistency ;)
- that should be easy and rememberable, and you can remember best these three: simple, strange or funny things
