What is Vulture-mode?
1.
Being in a situation where someone you definitely don't want to know what your computer is full of (i. e. parents or gf/bf), is standing right behind you staring at the screen and passively compelling you to self-restraint, i. e. not opening /b/ or pr0n, keeping messenger windows hidden just in case, and hiding embarassing desktop or icons (or embarassing icon names, such as "My Shit" instead of "My Computer") with randomly opened windows.
(1) "I can't open that link right now, Vulture-Mode."
(2) DM: "Pause guys. Vulture-Mode."
