Reclaimed use of the term "master bedroom," given that it is no longer socially acceptable to refer to the biggest bedroom in your house as a master bedroom (negative historical associations etc).
A masturbedroom is your own private sanctuary where you are free to self-love (with or without a partner), safe from being bothered by your dependents who inhabit the smaller bedrooms. A masturbedroom is a place where you can be an adult.
See "masturbasement."
