pulling an all nighter is commonly believed to be when you sat up until the sun rises doing homework then sleep in the morning. it is not. pulling an all nighter is when you stay awake for any reason whatsoever all night (give or take one hour) and continue into the next day.

Once I pulled an all nighter that lasted over 48 hours. I pulled one last night because I had a friend over. She passed out at 7 am.
