I love:
- Fuckhead
- Fuckwit
- Shithead
- Twat-stick
- You're so stupid, that if two of your braincells ran into one another, they'd both die of shock!
- Your mother is so fat, that when I said it was chilly outside, she ran out with a spoon.
- You're so fat that every time you turn around, your friends hold a "welcome home" party.
- Shut the fuck up you idiotic shitsmear on the arsehole of humanity
- Could you possibly be any more moronic than you are at this moment in time?
- What the fuck is your problem? Your parents not pay you enough attention as a child? Or were you just drop kicked as a baby?
- You look like the doctor hit you with a shovel when you were delivered, probably right after they discovered you were born without a brain.
- If I was hit with the ugly stick, the entire ugly tree must have fallen on you.
- Did you not pay enough attention in school or something?
- I've had more intelligent conversations with labotomy patients.
- I'm sorry, I didnt realise you were the victim of a labotomy.
- I'm sorry, I didnt realise you were a complete moron until you opened your mouth.
If I was to insult somebody I knew, because they'd push me too far, it'd be a tailor made critique of their personality complete with impersinations and reference to things they'd done in the past.
I don't make a habit of insulting complete strangers, but one or more from the above list is likely.
Actually, I very rarely insult anyone... mostly its when I'm driving and somebody does something stupid, then I come up with the most rediculous insults I can, it keeps me laughing and keeps me calm.
