Quick Definition: A creative way of opening a girl, or getting her attention without other people being aware of it.
In Stealth Attraction, Gambler talks about slowly touching the girl, as if by accident and testing her compliance towards him. This type of opening is very subtle and non-verbal. It allows the artist to speak a secret language that only women and players know. It also by-passes guy cockblocks and the necessity to befriend and talk to other guys in her group.
Tactile Opening methods are great but hard to think of.
