The act of reflecting on something before it has happened. To decide on what will have happened by the end of the day, week, lesson etc. This is usually followed by an attempt to make the events live up to your preflection.
Useful if you have to submit a report to someone (a weekly reflection for instance).
Preselection is a principle which dictates that women are more attracted to men that seem attractive to other women. So now because your girl 'selected' you, you must be a good mating choice.
In order to leverage the power of preselection you need to demonstrate that you are preselected by other women. Such as telling beautiful women stories of how you banged other beautiful women.
