The Mother Lake

A fictional body of water where many female actors, singers, performers, or other artists are jokingly presumed to have created or prepared their best work, which is then celebrated and discussed by their respective fan communities on social media. The phrase derived from Twitter users, particularly within online queer communities, speculating that their favorite female artists came up with their work through divine or spiritual intervention at this particular body of water. The visual description of the “Mother Lake” is open to interpretation - some view it as simply an enigmatic wooden dock on a mist-shrouded pond - others envision it as a sapphic 80’s Summer Camp on a lake populated by canoes and a serene sunset. It is thought that the “Mother Lake” contains healing or regenerative properties, which female artists harness as a source of energy to create what their fans consider flawless or excellent work.
Friend: “Have you listened to Fiona Apple’s album ‘Fetch the Bolt Cutters’?”

Me: Of course, she took a dip at the Mother Lake before writing that album.

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
