Shame Room

A room in the house used as a dedicated storage space for all of your uncompleted hobby and DIY projects. Typically this is also used as a junk room to keep other stuff that you have no other place for in your home such large inflatable penguins that you bought on impulse or that half-complete set of encyclopaedias that you swear is still useful.

See also pile of shame and stack of shame.

Person A: "I'm not up to much this weekend. Just picking up some new hobby stuff, adding to my shame room".
Person B: "You have a shame room?.." (assuming that it's something sexual, and wondering what the hell you consider a hobby)
