A week during the summer in which Discovery Channel airs its annual "Shark Week" and everyone on earth pretends to watch it and makes sure that all of their friends know by plastering stupid shit (e.g. Facebook status updates) all over the Internet. Usually no one really knows when Shark Week is until it actually happens because no one really cares about sharks any other week of the year. An overhyped show that everyone just claims they watch to look cool in front of their friends.
Facebook Status Update: "Shark weekkkkkk ♥ ♥ ♥ ♥"
"May the sharks be ever in your favor lol happy shark week 2012(:"
"Shark Week starts @9pm. Cant miss it!!"
"Oh, hey shark week!"
