pipeline

A female of mediocre physical attributes. Often used in context of slash (an attractive female) and backslash (an unattractive female). Derived from UNIX definitions (i.e. \ | /).

In college, Judy was slash and never considered pipeline. Her room mate, Audrey was as pipeline as you can get.

piper wiper

The act of fucking a girl in the ass, and as soon as the man cums, he pinches her neck very hard. This causes the woman's asshole to clench up, and when the man pulls his penis out, it is perfectly clean.

A piper wiper gets my dick nice and clean.
