Slang. A smelly, annoying, arrogant, person, who has no common sense, or ideas about real life and real people. Pips are stuck in a world where Friends, and Coupling are real, because he/she knows no different.
An imaginary person that possesses some qualities of a real person. Once thought to just be a collective figment of everyone's imagination, recent discoveries show that he is, in fact, a being formed out of all the acid trips of the 60's. The power of this formation causes him to be seen by completely sober people. As well as letting him manipulate objects, and play the trombone.
