Get the as if mug.
Short for "as if that was true," "as if that would really happen," or "as if she'd really agree to that." Basically, it means it'll be a cold day in hell that the idea or event is true or ever will be. It's a hipper version of the 80's expression, "Yeah, right!"
Enriched after selling plasma, old impoverished Nathan approached young, smokin' hot Angela and asked her if she'd like to have dinner with him at the all-you-can-eat buffet: his treat. After throwing up a bit in her mouth, she rolled her beautiful blue eyes and blurted, "As if!"

Get the as if mug.
Commonly used exclamation, typically amongst Sixth Formers, used in a sarcastic manner when faced with a situation that they either love or hate.

Ie, they shout "as if", often repeated by the action it is suggested they partake in, and exclaim whether they will or will not do it, and whether they love or hate it!

Can also be used if something is completely true, but you would like to draw more attention to it.

See examples.
Cassie: Are you going to LeedsFest this year?
Jordyn: As If I can't go to LeedsFest! HATE THAT!

Lameass Are you going to LeedsFest this year?
Messy: No, but Tom is.
Lameass: Ahhhh! As If I hate that so much!

Monique: As if we're going to Paris in two weeks. Oh wait. We are.. LOVE THAT!
