AKA “Social Hook Point”
Quick Definition: The point during an interaction when a woman decides she is interested enough in the PUA to continue interacting with him.
A hook point occurs when the girl or group gives the PUA an IOI and starts becoming more interested in him. It is the point where the perceived value of the PUA has become high enough for them to be genuinely interested in who he is. Reaching the HP early is important to keep from getting blown out.
