A period of time in which a usually unfuckable man goes on a hot streak with women. The success is not due to any gained knowledge or attractiveness, but rather to the application of the law of large numbers by the man in social settings. By trying to hookup with as many people as possible, rejection is inevitable, but you will be able to get a percentage of these people to fuck you. The streak must also be precluded, and followed by sexual cold streaks.
