Third Date Rule
The third date is generally considered the "sex date." It is the average number of dates until it is deemed proper and acceptable to have sex with a new mate; therefore, the Third Date Rule is the implementation of this theory.
I better go buy some new underwear and shave my legs; according to the Third Date Rule, I should get lucky tonight!
