Disqualify examples from PUAbible site: Disqualify her and tell her that she's not your type, or disqualify yourself and tell her you have a girlfriend/have a small dick etc.

Qualification example: Ask her what else she to offer you has other than her beauty

PUA sites seem to advocate using these methods early (particularly disqualification), soon after the open when, presumably to spike attraction in her.

I've found using it this way to not really help, although I have found it to be a useful tool to use when a girl is instantly into you after the open and is chasing you etc (like most game theory, it seems to work on attracted girls)

Do you personally wait until IOI's from her etc, or do you do it by the book and use them techniques on unattracted girls (or at best, aloof/cold girls)
