Curse you and your Alt + F4!

Once uttered by The True Master, and memed about since the original occurance. Jokingly, an individual pretended to start to press the computer command ‘Alt + F4’ on the laptop The True Master was using, leading to Him uttering this amazing phase.

‘Alt + F4’ as a computer command relates to the computer button ‘Alt’ being pressed, and then subsequently ‘F4’ after. This causes the current open window to close, and may close without progress or work being saved. The True Master did not want His window to close, so He had to utter this phase in a successful attempt to halt the action.

Person 1: *pretends to press ‘Alt + F4’*
The True Master: “Curse you and your Alt + F4!”
