the midnight wall

that time, usually around midnight, when one may get sleepy and end their internet session (or just doze off in their chair). if the victim can overcome it they stop feeling sleepy sometime between 12:30 and 2, when their sleep deprived brain stops telling them to go to bed and can proceed with their all night internet/gaming session

jeremy: why do you look so tired today?

shaun: i was up all night playing WoW. i considered going to bed around midnight but by 1:30 i had broken through the midnight wall and i went till 5
