The Roller-coaster Principle

An analogy between activities of a sexual or romantic nature and a roller-coaster, or any amusement park ride. According to this philosophy, the engaging in sexual activities with a partner one does not find aesthetically satisfactory in order to receive a similar treatment from his/her far better looking friend is equivalent to waiting in line (a mundane and unpleasant activity) in order to get on a roller-coaster (a thrilling and exhilarating experience). The roller-coaster principle may also be used to describe the opposite: waiting in line for an amusement park ride that ultimately is not worth the wait. Details of the roller-coaster riding experience also directly apply to the metaphorical analogy. For example, vomiting on Kingda Ka would be the equivalent of vomiting while having intercourse with Meghan Fox. The Roller-coaster Principle, so long as the roller-coaster is in fact superior to the wait in line, exempts any male or female from being ridiculed for "waiting in line". Can also be defined as "exploitation and manipulation".
