Pantie Dropping Power. A non-numeric rating system for cars based on how quickly women would remove their panties at the sight of that car. This system isnt a measure of a car's engineering merits since women know nothing about cars, so a very good car have low PDP or a very lousy car can have high PDP
A Veyron has the highest PDP of any car in the world. An Audi R8 has very high PDP, while your Hyundai Atos doesnt. Actually no asian car has any PDP of any sort. Honda Civic owners go home alone very often. Mustangs are examples of cars which are actually rubbish, but have high PDP.
Pants down piss. Being a grown man, and dropping your pants to your ankles and peeing at a urinal in a public setting. Invented and introduced to the world on youtube by Jack Weaver.
Parallel Distributed Network
An informationprocessing system that uses input units linked to hidden units which are linked to output units to transmit, store and process information. Each input unit is something like a neuron and the links between units are known as connection wieghts which are akin to a neural synapse.
Connectionist Theory asserts that a PDP network is the best representation of the human brain structure.
