desktritus
Pile of useless files cluttering up your computer's desktop.
Why don't you delete some of these old downloads and unused shortcuts once in a while? I can't even see where your 'My Computer' folder is within all this desktritus!
desktritus
the random accumulated tchotchkes, stationery, and detritus found on/in a desk. From desk + detritus = desktritus.
It was only when I left my job that I realized how much desktritus I'd accumulated in four years.
