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".

Guy 1: As one of my closest friends, I simply cannot allow you to accept that female's offer of fornication. She is simply horrendous!
Guy 2: You mustn't forget that said lovemaking increases my chances of performing similar acts on her tantalizing and voluptuous compatriot without need of Roofies!
Guys 1 & 2 in unison: THE ROLLER-COASTER PRINCIPLE!
*Highfive*

Roller coaster

to have sex with a girl from behind while her head facing down towards the bottom of the stairs, you then proceed to punch her in the head and ride her all the way down to the bottom of said stairs.

I rode her all the way to the bottom of the roller coaster!

There once was a guy from Bel-air
who was doing his girl on the stairs
the banister broke
so he quickened his stroke
and finished her off in mid-air!

Coaster enthusiast

Dangerous individuals. It’s highly likely most were bullied as children and have undergone some deep trauma in their lives.

A lot of them are perverts. Some trans enthusiasts are known to pray on the vulnerable, seeking out their pray and obtaining their addresses by ‘free photo giveaways’ as a ploy to know where their victim lives.

If you ever come across one, please be careful

“Did you see the free photo giveaway that Jackie the coaster enthusiast posted on Twitter? Yes mate, it’s a trap, stay safe & don’t give them your personal info”
