Just say thank you for the compliment.
a good comeback would be " look who is talking" "there's a mirror hun, woops! it broke!!" "haha i wouldn't be talking if i were you."
you could say at least I'm not conceited (conceited means in love with yourself) i would know this because I am super great at comebacks
Tell them thats's out of your depth!
At least my head anit square like yours!
"This is an A-B conversation, so C your way out." "What did you have for breakfast? Annoying Flakes?" "Who [urinated] in your Corn Flakes?
Like if someone says '' your stupid'' say i know you are or thanks im glad you notice''
if somebody says f you just say "maybe later" or something like that
A good classy comeback for a girl is "that is why there is only one me".
Says the murderer....
There are several books you can purchase either in Barnes and Noble or via the web for funny comebacks. A site called silentreed in hubpages has some realy good ones.
When a guy tells you your chest is flat simply tell him his dick is small. Another good comeback would be Òmost guys have a bulge in their trousers, where is yours?Ó
