Good responses against gamebusters?

[YesNo]

Recently I was on a party with my new girl friend (8+ by the way).
But there was this guy, let's call X. And he was making,
very dumb, fun of me:

X(carry a bottle of applejuice-vodka): "Look it's mark's urine."
His fellows laughed loud.
However I decided to ignore. But that doesn't stop him (no wonder).
So I said, sarcastically: yeah! Does it taste?
X (looking at the bottle): "Uah, smell very bad! What have you eaten man?"
And again, his fellows laughed loud.

However to keep it short, I've discovered that since I'm more sucessful there are more people like X which try to bust my game.

Are there any good responses (especially for dumb) busts like above?

thx

In all honesty forget about trying to come up with a way to put down the haters.

If you really want to then just slap them with a trademark saying of your own like "At least I'll be leaving with 2 girls tonight bro" or something like that.

X(carry a bottle of applejuice-vodka): "Look it's mark's urine."

"Dude, why u hangin onto that stuff?"
