can be good and bad. Nicknames are very interesting. I have seen that in most cases, you do not pick your own nickname. It is gracefully 'bestowed'(heavy, heavy sarcasm) upon you by friends or whoever happens to be giving you this name. Some nicknames, come from things that person does or says, or looks like, or even acts like.
But in some cases, like mine, the nicknames are pointless, and make zero sense.And the people who gave you the crazy nickname in the first place, are crazy themselves. Oh, and don't even get me started on nicknames your family or grandparents give you. Those are almost always the worst and most embarrassing.
