So what is it called if someone is 35, lives with their parents, and has never had a job in their life? Not even a part time job or anything. Literally never worked for a single dollar. Not trying to start a fight, just genuinely curious and want to learn.
I had a friend like this and the only word I could find to describe him was lazy. Eventually I had to cut him out of my life for completely unrelated reasons, but this was where he was at the last time I talked to him maybe 4 years ago.
He would complain that he had no money to buy things and have fun with friends, and I would suggest something like a part time job at a fast food place, or a grocery store, or anything. And he would say no because those types of jobs are beneath him, and he wants a good job like being an artist for video games. But he wouldn't take the time to learn those things and develop those skills. He would just play video games for 16 hours a day, only taking breaks to eat and smoke weed, and then go to sleep, rinse and repeat.
