Who is that pua with 2 rules?

[Stephen89]

I forget the name of the pua with two rules:

1) don't give a crap what she thinks
2) who cares less has the most power

This pua was a bit chubby and was mentioned in the game?

EDIT: His name is David X

Agree it was David X.

I thought* his rule 2 was "You are the most important person in the relationship."

*I'm rusty. This is early PUA stuff.
