The act of what the name implies - doing absolute shit for no good reason at all other than to make yourself eventually feel fat, uneducated and unhealthy.
Despite this outcome, doing nothing can be the most productive form of what shouldn't be entertaining. Many men enjoy participating in the act of doing nothing, and the act of doing nothing in the best way can possibly be seen through this quote:
"“…What I like doing best is Nothing.” “How do you do Nothing?” asked Pooh after he had wondered for a long time. “Well, it’s when people call out at you just as you’re going off to do it, ‘What are you going to do, Christopher Robin?’ and you say,”Oh, Nothing,” and then you go and do it.” “It means just going along, listening to all the things you can’t hear, and not bothering.” “Oh!” said Pooh." — A.A. Milne (Winnie-the-Pooh).
Christopher Milne assumably went and wanked non-stop after this, as he was initially talking to Pooh about doing nothing. Wanking, or masturbation is prevalent within the men's form of doing nothing, and can often lead to soreness of the testicles or penis.
Sam's Friend: "Hey Sam, did you study for Geography last night?"
Sam: "Nah... I just spent the entire day doing nothing."
Sam's Friend: "Oh... what did you do?"
Sam: "Wanked my brains out, whilst p00nInG n00b$ on COD and spent loads of time uploading the definition of "Doing Nothing" while trying to make it sound funny."
Sam's Friend thinks: "Fuck me, he is a loser. Damn that pimply-faced son of a bitch with too much spare time on his hands which he wastes copiously."
Matt: So Greg, what are you doing today?
Greg: Oh, i'm doing nothing much really.
Matt So, in other words you are going to masturbate vigorously all day.
