Okay little buddy, so a nickname is like a special name that people give to someone they know really well. It's usually shorter and easier to say than their real name. Now, the nickname "lota" is like a secret code or word that only certain people know about. It's kind of like a special club or group that only people who use the nickname are a part of.
Now, where did the nickname "lota" come from? Well, that's a bit of a mystery. It could be that someone had trouble saying the person's real name, or maybe they just thought it sounded funny or cute. Whatever the reason, the person with the nickname "lota" probably likes it because it's something special that only their close friends or family use.
So remember, a nickname is a special name that people call someone they know well, and "lota" is just one example of a nickname that has a special meaning to the person who has it.
