Most guys run social circles of some sort.
Often there are a few girls in your social circle who are good-looking but not super into you. Or they might be interested in you but they're not compliant enough you're able to get them out onto dates.
If you're also meeting women from places outside your social circle, there's a tactic you can leverage to use the power of preselection to get women in that circle chasing after you.
We'll just call this 'social circle date showoffs'.
It's both simple to do, and deviously effective.
