It might not be the context you're looking for but I do this all the time, strictly as a joke to get laid and it works great. You've just got to not be a total spaz about it, read the social cues and time it right.

Next time you wanna talk to a fit girl at a house party just plop down on the couch next to her, introduce yourself and strike conversation, and then bam, hit her with something like,

"I'm actually proper annoyed you're here"

Why?

"cos now I have to be handsome and funny all night"

And when she fishes for the follow up compliments and asks why again, just act all deadpan like,

"Would you mind if I was just a tiny bit in love with you?"

If it's awkward you can laugh it off and act like she's an idiot for not getting your joke and if she giggles and digs it you're in there like swimwear,

Make appropriate amounts of eye contact, don't fidget and be at least 3 points in range of her score out of 10.
