Examples of plumber’s crack
Where does plumber’s crack come from?
A stereotypical image of a plumber is of a heavyset man bent down beneath a sink with a tool belt around the waist. The position and belt tend to pull down the back of the pants, and if those pants are too tight, they can accidentally reveal the “crack” of the upper buttocks. This exposure has been called builder’s bum in the UK since 1988 and plumber’s crack in the US as early as 1992.
Some of the earliest instances of plumber’s crack, though, aren’t about plumbers but about the 1990s fashion trend of tight-fitting, low-rise pants, as a 1992 article in the Seattle Times says of a fashion show featuring “painted-on paints.” Plumber’s crack appears in Nicole Grey’s 1993 novel Daydream Believer, while plumber’s butt is referenced in a 1994 issue of Sports Illustrated, followed by plumber’s crack in Jim Humes’s 1995 snowboarding book Boarderlands.
Professional plumbers aren’t above the expression, however. In 1997, a plumbing company playfully marketed themselves in the Seattle Scroll with “No butt crack plumbers.”
Visual references to plumber’s cracks in cartoons, movies, TV, and other media largely spreads in the 1990s onward. Cartoons in particular popularized the trope of an overweight plumber bending over into the sink, inadvertently revealing his butt crack, usually to the visible discomfort of the protagonist.
Who uses plumber’s crack?
The term plumber’s crack is colloquially used in speech and writing in various humorous or uncomplimentary situations when a person’s pants sink too low in the back. For men, plumber’s crack is often used when pants are too loose and saggy. For women, plumber’s crack is frequently used when pants are too low-sitting and tight.
Plumber’s crack has been extended as an insulting noun phrase for a burly, slovenly, working-class man, often portrayed as socially ungracious or oblivious (e.g., I’m not going to talk to that plumber crack guy over there. Look at the stains on his shirt and how dirty his fingernails are.).
A more neutral term for plumber’s crack, which is generally comical or negative in connotation, is buttock cleavage, while a formal term is intergluteal cleft.
