Rate of Perceived Exertion (a scale from 1-10 that measures how easy or difficult you find the intensity of an exercise you’re performing — not to be confused with a similar secret guy scale that measures how easy or difficult it is to bang a chick, which is then passed on to other guys to let them know how much effort they have to put forth before banging her too). see also: TEAMWORK
