Most offensive insult?

[danmer]

hax

[Coolio]

The 2 most offensive insults would be you
"****in nooblet."
"This is a offensive insult."

[Clawbug]

Easy way to get killed is to tell a girl she is fat.

[Smegma]

Unless she is fat, then she just cries.

Or ones that think they are fat.

[The Specialist]

Probably racial slurs.

[RabidTreeFrog]

You, my friend, are a waste of fucking semen, your mother should have swallowed you.

works every time

[Mangled*]

That note makes me want to create one of a similar vibe...

okay..

Of all the sperm in your dads scrotum, how the f*** did you make it to the egg first?

Not particularly offensive.. although if it's a fat person you could mention that they are so fat that when they were a sperm, they would have been the only sperm in the world visible without a microscope.

if you keep my mom out of this, I'll keep this out of your mom. (points at crotch)

"I'll do your mom" insults are incredibly stupid.  Naturally, this guy says why better than I can:

People who, when they can't think of a single intelligent thing to say in an argument, still use retarded "your mom" insults thinking that they're the ultimate stab. You fucked my mom? Lucky you. She's 59. Who are you trying to insult, me or yourself? You really "0wned" me there, retard. Brag some more about your sexual escapades with a post-menopausal woman.

[Smegma]

You're the poster child for abortion.

[BondJamesBond]

My greatest insult is silence. Negligence. Why demean yourself to their level, when you are clearly much too busy and much to superior.

[Xxypher]

Your adopted and your parents hate you.

[Lord Frunkamunch]

Your adopted and your parents hate you.

And I can tell that over the internet by the way you type, and still expect it to be offensive. You're also gay and a virgin because I said so.

[Mangled*]

Your mother is frigid.

[PANZERCATWAGON]

Those greasy papist coon darkie raghead wetback fudgepackers were trying to jew us down on cheap chinky crap. Bloody Indiangivers.

[Blazing Tiger]

You throw like a girl

[ThunderPantz]

You smell/look like rotten pig shit stuffed into a horse's cock.

This bad?

[Lord Frunkamunch]

No, just laughable. I'd say RabidTreeFrog's was the best so far...
