I'll try to explain what I think of the following two things: what people mean with it and why they say it.
[edit]
In this post I'm only talking about the "Geez, get a life, (wo)man" kind of "get a life", if you know what I mean <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />With "life", I think most people mean "real life interaction".
(Add "I think" to every sentence following next -- This is not something scientifically proved <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />, it's just what I think <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> )
Most people live for relations. In fact, most people are obsessed with relations: I could bring it down to Freud's favorite subject, but I don't think I need to, to have you agree that most people can't be on their own for a long time, without starting to feel tired, sad and/or lonely.
When I say most people live for relations, I mean both intimite relations and "mere" friendship. Most people feel bad when they don't have a partner. And you don't experience hugs, kisses... (and the usual consequence of those <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> ) over the Internet.
As for the friendship (and partner as well, of course): relations over the Internet are not valued as highly because there is no physical contact. We're animals, and until telephones and Internet etc showed up, contact meant actually being next to eachother and communicate. Even shake hands or give eachother a how-do-you-do kiss.
With physical contact I also mean body language: very important - but missing when over the Internet - aspect of communication. It's like we're only communicating half - it's not our "natural" way of interaction.
When someone tells you to "get a life", it's usually because you've done or said something that could indicate and is interpreted by that someone, that you've been without that kind of contact for too long. It doesn't even have to "seem" that long, any small indication will make us assume what we want: we live in a time where we like to exaggerate - and more importantly, don't we just love preconceptions? When we say to someone "get a life" we're also hoping (s)he's actually someone who'se spent too much time on his/her own: that would make us less "nerdy" than that person, and don't we all love to be "better" than the rest?
By stating this I could come across pretty biased myself, but let me add I'm not saying it's
always the same reason for why someone says "get a life". But I think it's a very common reason and a valid explanation in many cases.
Well, I think, anyway <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
