A steady source of sex partners. Usually diverse in geography, it's made up of people willing to have sex with no emotional ties. Works best when they don't know each other.
Is that one of his fuck buddies? Oh yea, he has so many women in the Pipeline most of time his phone rings its a booty call.

Wow! I'm having a hard time managing the Pipeline. Can I send some your way?

Did he fuck her? No, she wasn't ready. So he put her in the Pipeline. (ie. He "pipelined" her)

when you cannot keep your loud ass mouth shut about anything when someone tells you either a story, secret, etc. You have to tell everyone and their mother what happened to and to who it happened to. Once you tell them it just works down the pipeline.
I cant tell rafter anything at all anymore. All he does is pipeline all day long.

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.
