CPI
The Cost Per Insertion, referring to the price required in order to complete intercourse with someone of the opposite sex. Normally worked out by adding overheads such as meals, cinema tickets, travel etc. then dividing by the number of times one has had sex with that person. A low CPI obviously denotes a slut while a high one denotes a high maintenance girlfriend or expensive hooker.
Dave: What you're girlfriend like?
Sam: Well she's certainly no cheap slut, with a CPI of 120 quid I may as well get a hooker.
Dave: Yeah, my bird's much better, CPI of 20 and I get to take her up the shitpipe.
