Yes, the MM works, depending on your personality, and the type of women you are trying to attract. A lot of people here dont like the MM, but I think it is a funny and fun way to play around with women.
However, I have found it to work best when you are honest about it. You can tel the girl you are using it, and make a funny joke out of the whole thing. You can go as far as to make fun of guys who use systems to pick-up women, which in actuality is a technique for pick-up in itself.
This is how I would advise using the MM, especially to the guys here who are overly concerned with the recent exposure of pick-up. If you're not trying to deceive people and get away with something, what are you worried about?
