I like "Lint Licker"

coward.

indecent proposals

i experienced it and it was the most disgusting and insulting thing someone has done and said to me.

George Bernard Shaw to Winston Churchill:
"I am enclosing two tickets to the first night of my new play, bring a friend... if you have one."
Winston Churchill, in response:
"Cannot possibly attend first night, will attend second... if there is one."
BRILLIANT.

What a good question! One I remember is, You're pathetic.

I like the one from Shaw to Churchill

I thought the Shaw/Churchill thing was the most dry and lifeless thing I have ever heard:P It's like talking in binary code and then saying "Oh, I really got him!":P

"Cootie queen! What the french, toast? Who are you calling a cootie queen, you lint licker?" --love that commercial:P

Simple..."You're fat!"
Worst thing I could possibly hear
Or wait
"You're a failure"
They rank quite evenly in my book

"well i'd hate you even if i didn't hate you" - Patrick. From the show Spongebob squarepants.
