Builder’s crack, plumber’s bum, the coinslot, bottom cleavage…
No matter where you go in the world, there’s an expression for the unfortunate moment when a tradesman or woman bends down and reveals the top end of their backside.
In French, it’s called the plumber’s smile (sourire de plombier) or even the “mason’s line” (raie du maçon).
“I’m not changing the world… maybe just a bit. It’s not like I’ve found a cure for Aids – just for the builder’s crack.”
