When your brain is so scrambled after an all nighter that you have actually convinced yourself that night is spelled "knight."
Darren: Dude, how did you manage to achieve the impossible and actually manage to fail a Microeconomics test?

Daniel: Bro, I have no idea. I even pulled an all knighter for the test!

Darren: No wonder you failed the test....

Get the All Knighter mug.
Pulling a "Dark All-Knighter" is when you go to see the premiere of the new Batman movie, The Dark Knight, on Friday morning at 12:01 A.M. or 3:30 A.M. and then stay up all night to go to work that Friday morning.
Yo dude, I went to see premiere of the new Batman movie last night at 12:01 A.M. then had to be in at work this morning at 8 so I pulled a Dark All-Knighter.
