Guy with a different hobby: "Whoah, what a great insult. You sure told me."
Egotistical Tw*t (blissfully unaware of the sarcasm shown) "That's right!"
Guy: At least I don't change the subject when someone asks how many friends I have.
Retard: Go get a life.
Play video games like World of Warcraft or any RPG for that matter.
Like things that aren't really popular (certain music, tv shows, etc.)
Spend much of your time on a computer.
Do not have a boyfriend/girlfriend
In reality, these people do have lives, it is just not in the same interest as the person telling them to get a life, so this "insult" is not affecting them.
Person 2: Actually, I do have a life. I have a job that I love, and I have a great family that I come home to every day. I like to play WoW because it is fun and I get to meet new people on the internet!
Person 1: No, you're a nerd because you play WoW and you're probably 45 years old and live in your parents' basement.
Person 2: Okay, even though I just explained my life to you, I already told you that I have a life. Just because I play WoW doesn't mean I don't have a life, you ignorant fool.
