A function/shortcut used in the Windows operating system. Pressing the
Windows Key and the letter 'D' simultaneously will minimise any folder/program/window that is on the screen at the time.
Due to this
function's popularity with risk-taking pornography fanatics (to quickly hide evidence of unscrupulous activity), it can be humorous to shout "
WINDOWS KEY D" while entering a friend's room when you know they are using a computer.
Bill
swifty entered Scott's room while shouting "
WINDOWS KEY D" (
