Uh no, back in high school one of my acquantainces held a lie for something like 3 years that he had a girlfriend named x that went to y school. My friends and I ended up seeing the yearbooks for that school. We couldn't find a single person at the school with his girlfriends name. He tried to say that her real name was actually w, and I kind of just stopped talking to him afterwards. Never learned how that played out with people closer to him.

It's a real thing people lie about.
