My response: "I am not antisocial. I am introverted. Solitary. Maybe even a little gruff and unapproachable sometimes, at least when people like you interrupt me in the middle of something like you're doing now. But I recommend you pick up a fucking dictionary and look up the term 'antisocial'. Or better yet, I'm at my computer, let me do it for you.
Here.
Antisocial (adj.) 1. unwilling or unable to associate in a normal or friendly way with other people:
2. antagonistic, hostile, or unfriendly toward others; menacing; threatening: an antisocial act.
3. opposed or detrimental to social order or the principles on which society is constituted: antisocial behavior.
4. Psychiatry. of or pertaining to a pattern of behavior in which social norms and the rights of others are persistently violated.
OK, I might grant you "unwilling or unable", but it's more because I'm just not in the fucking mood right now. Nobody should be forced to socialize, because that means you just flunked definition #2. Order is my highest societal value, so there goes #3 into the shitter, and you also flunked definition #4, which means according to psychiatrists, YOU are the one with antisocial personality disorder. Now go check yourself into a fucking nuthouse. I'm busy here."
