Man caves are private spaces typically used by men for leisure activities such as watching sports, playing video games, or just relaxing. They are often located in basements, garages, or other areas of the home. The terms 'DENS' and 'LAIRS' are often used to describe man caves, as they are typically dark, cozy, and secluded. DENS are usually smaller and more intimate than LAIRS, which tend to be larger and more spacious.
