Indeed, such is the level of this obsession that one doesn't understand where the guy's hands end and where the game consoles begin. Forever glued to the gaming set, swearing at the opponents and doing almost nothing else (in life) is your visual cue to know it's a man-child before your eyes.
But actual grownup (by age) men-children (by nature) have these incorrigible habits which can drive any responsible person up the wall. Seriously, would it be so bad to own up to the room you own, men-children?
So it's either the cereal stash or innumerable precooked meals sent by his mother or girlfriend. Which would be praiseworthy if he'd be doing a 20-hour long job, which isn't the case.
Asking him to 'settle down' is a futile exercise anyway, so don't get your hopes too high on that subject.
A man-child wouldn't get half his things done if it weren't for his mother. Sometimes you feel more for the poor woman than her son who forgot to grow up.
If he thinks 'toilet jokes' will have 'people laughing till water sprouts out from their noses'...wouldn't we all agree that's gross?
Expressing anger in a restrained manner is an alien concept to the man-child. And his fights with his friends are, literally that. FIGHTS.
Well-mannered children are better at behaving like a 'grownup' than this man-child, don't you think?
