Ass mosaic

[Ernesto]

The indentation on ones ass that occurs from sitting [unclothed] on a patterned surface-namely pavement-for an extended period of time. The said indentation usually resembles a sort of [mosaic] that might be found hung in an ancient Roman villa; next to a frescoe, perhaps? Most often occurs whilst smoking nude in a jacuzzi of [suds]. Inappropriate in every circumstance.
