Plumber Night 

Any night that you have extensive sexual intercourse with no ejaculation. Named after the situation frequently found when you order a plumber: you stay in all day, and nobody comes.

Bob: Kelly came round last night.
Roger: I take it you left her looking like a Painter's Radio?
Bob: I couldn't get that far mate. Neither could she.
Roger: Ah, sounds like you had a Plumber Night.
Bob: You know all the cool sexual pseudonyms.

plumber's nightmare

A worst case situation for a plumber, on a job with no tea, coffee or biscuits supplied by an unthinking householder.

Fuck these people, no tea all day it's a plumber's nightmare, I will go and piss in their water tank.
