someone that freeloads in a basement and is oblivious to society having no social skills.

also an ogre that sits in someone else's basement eating and playing video games or watching movies

a childesh-like adult who can't get a women because he is a lame-ass loser who slaps his lips and eats like a beast
Bally wally is still down in the basement eating and playing video games using our electricity and hasn't paid rent for six fucking months.

Bally wally is like a fucking child because he is a basement dweller and stinks the place up because he is like a shit stain that won't go away.
