I had a girlfriend tell me this shortly after I broke up with her.
I think I saw this one on the boards somewhere.
“Jesus may love you, but I think you’re shit wrapped in skin.”
Also calling someone a “Stunned c*nt”, male or female, seems highly insulting to me.
My fave: Why don’t you attempt aerial fornication with a laterally rotating toroidal pastry?
Of course now that I work in a donut shop I ask that customers not do this while I am there.
I also did a thread awhile back looking for some good ones. A few did turn up, so check it out if you like.
I will definately have to use these sometime. Considering the intelligence level that I have to deal with every day at high school, I can’t wait to see the confused looks on people’s faces.
Good heavens, I made the Page O’ Flames!
Why doesn’t anyone tell me these things?

Sorry guys, I’m not a homophobe but I think the insult “Boner Breath” is funny.
Your mamma’s so fat she’s got smaller fat women orbiting around her.
Your sister says your wife’s no good in bed.
Apparently it’s Australian in origin and designed to make the batter’s brain freeze up during cricket games. I like it 'cuz it’s layered.
I do like leander’s.
A girl I know is always partial to, “Hey! GRAB A SPOON AND EAT MY ASS!!!”
Love it! Will have to use it at some point.
I always favour a Blank Look. Then something like; ‘you, sir/madam, are an oik’. Hehehe, oik.
Or, my personal favourite, ‘You are a waste of my time. Fuck off.’ Simple, but delivered effectivly, it’s very crushing.
Pfft. Five times here.
I am that damn good. 
Not terribly withering, but I’ve always been partial to:
“You have GOT to be the biggest waste of protoplasm on this Godforsaken planet.”
Of course, begining a rant against someone with the phrase, “LISTEN UP, FUCKSTICK!!” usually turns heads, anyway.
