Hmmm let me think of a common thing someone says in a malicious manner to invoke a negative reaction
ah yes
"you should just come out of the closet"
"why are you asking, are you interested in me or something
because, and I'm sorry to say this, I just don't like you that way mate"

that shuts them up because you're immediately taking the offensive and asking why they've asked
the normal reply I then get is nervous laughter because they don't want a bad rep

Well I find this thread insulting a bit, but I LOVE comebacks.

Umm.......this one is pretty common but

Guy: Why are you stupid?
Me: You were ALWAYS stupid
Other guy: ?!?!?!?!

[Username] I hate you
[Kittycattfm] I love you ^-^ <3

when someone insults me:
"that's cute"
"you must be so excited, seeing that this is the first time you've used your brain"

"Shut up, you'll never be the man your mother is."
"Your birth certificate is an apology from the condom factory."
