If you describe a person Pipe Layable, then it is stating that you wish "Lay Some Pipe" on them, meaining you yourself have to have some "Pipe" to lay, inside a Pipe Layable's "Pipe Lining". Derived from Victor from Big Brothers quote, "You can call me the Plumber, you know what I'm saying, I like to lay the pipe on the women"
Abbriviated to "PL"
Damn that Girl is a real Pipe Layable
Shit that is a one Pipe Layable Lady
