A derogatory name for one who shows an extreme lack of any effort in life. More often than not, an Alvenatuh will be a jobless mongoloid who does nothing but sit on his ass, play video games and watch anime all day. The Mommuh always owes it to him.
Wow, that guy has no job and makes his mom buy him whatever he wants. He's a real Alvenatuh.
