Meme: Friday Afternoon
Origin: Olafur Waage
Cultural Height: Friday in Iceland
Background: Friday Afternoon is generally recognized as the period of the week when programmers like to slack off (more than usual) and begin an early unwinding from the past week's worth of not doing anything of great importance or productiveness. This time period has often resultedwould result in users posting "laid back" or "fun" questions on Stack Overflow, meeting both great acclaim and massive community outrage. (Note: such questions are no longer welcome there.)
The Friday Afternoon theme has now gained more traction on Meta Stack OverflowExchange more than any other site in the League of Justice. It is not uncommon to see multiple "Friday Afternoon" questions posted throughout the day. This resulted in the creation of the tag always-friday-in-iceland, which used to be quite popular until one sad day it got marked as a synonym of fun and fun questions in general were curtailed.
There is no set time frame which Friday Afternoon falls, because as once said in a song, "It's 5 o'clock somewhere". Because of this, you are just as likely to see a question posted early on Friday morning (depending on your time zone) as you are to see one posted in the afternoon.
