Does "Negging" actually work? And if so, why do you think that is?

Does
The concept of "negging," is a trick that pickup artists use. They give a girl a compliment, and then take 50% of the compliment back. The theory is that the woman will now struggle to get the other 50% back. They will move mountains just to get that 50% back. So while all the other ass-kissing guys are vying for her attention, she's ONLY interested in the one guy who stole 50% of her compliment. (Google it) It's referred to as a "backhanded compliment."

Tom: Wow, that's a gorgeous pink top you're wearing. My grandmother had the same one.
Bambi: Umm, thanks.

Tom: That pink top of yours is very sexy, but the color doesn't really work for you. I think blue is your color.
Bambi: I almost bought the blue one. I might see if I can find the receipt.

Tom: Please don't take this the wrong way, but you remind me of my mom.
Bambi: Thanks?

Tom: I love your nails. Are they the fake kind?
Bambi: No, they're real.

Tom: Your eyes are gorgeous, are you wearing colored contacts?
Bambi: Yes, but I'm glad you like them.

What are the pros and cons of negging?

Cons: This PUA technique is said to only work on dumb girls.
Pros: Most all girls are dumb. (same with the guys, of course)
