Term used to define the heightened sense of awareness one has to a subject following their initial exposure to it.
Josie: Hmm well I still have some ICY-HOT left in my car from badminton camp, want to PCR?
Ian: Yeah we have time for 60 cycles of hot then cold
A PCR most often occurs during the morning after the butt sex. The poor violated, shacker girl leaves the apartment and begins her journey on the walk of shame. It is at this point in which the male, comes out of his room, with a grin of victory and self satisfaction, and releases the evils of his ass into the Earth's atmosphere. After holding in the all of his farts, the PCR can occur and his ass will stop hurting.
Oh yea I did!
