A basement dweller, much like a hikikomori, lives inside their guardian's house and often do not pay rent, have no job, have no dreams of pursuing education, and are often obsessed with anime, video games, manga and often have a unhealthy life style of playing video games all day, neve working, going on reddit, and eating junk food all day. A majority of these people are misogynists, men, and obese mainly living in the US or Canada but are slowly becoming mainstream and a popular trend in countries and becoming more present in today's society.
My uncle is a basement dweller. All day he sit's in his mom's basement and hasn't had any reaction with anyone other than in his mom in real life in 29 years.
