Actually... I have a reason to question it. It's called experience. I don't know about the Vegas whores Mystery was building his book on. But here, in Hungary, anything bad you say about a girl's cloth is considered a HUGE insult. You're questionning her style mate, it's no good. This whole concept of negging is also a very dangerous field. Most of the times you will just come off as a douche. It can be done properly but it's just much easier to avoid it. Here's my point:
When I compliment a girl, I mention characteristic features not her appeareance. So if I want to be playful, and go little poky, why would I pick on her appeareance? To make fun of the things she's doing right at that moment is way more subtle, socially more acceptable, even more funny, and in my experience much more effective.
I have a reason for hating these kinds of negs dude. I've failed with them countless times. From the most subtle to the most outragous one I've tried almost every one that is listed in that book. Actually...the more playful ones are really good. Like the nose wiggling thing, I love that. But several are just either plain shit or designed for the vegas ego queens(which I'm not interested in in any ways no matter how hot she is) Why bother calibrating this shit, when being JUST playful is not only easier, but more effective as well?
TRUE! being playful also puts me in a bubbly mood which she can have fun with, If i try and neg, deep inside i feel abit guilty, not playful. Which kills the fun for me, Why would i want that? Playfullness is the way to go
