Great comeback, you are sharper than a sponge, i have not got an answer for that one
A comeback? No lad, I'm not having an argument that goes to and forth. I told you to be quiet, as you were (as always) talking utter cunt dribble. You've responded with feeble attempts at what I can only imagine you consider humorous retorts, cumulating in the ever reliable argument 'slam dunk' that is "Great comeback".
So carry on with the remarkably curious attempted put downs, they are a tad more imaginative than "Osman is shit" after all.
