look up any word, like fleek:
The period of time right after school gets out, and into the greater part of summer, when people on Facebook must one-up everyone's posts to try to show that they're having a better summer than everyone else.
Person 1's Post: Had a fun time last night, I love summer.

Person 2's Post: Last night was INSANE, this summer's gonna be awesome!

Person 3's Post: Yesterday could NOT have been any better! And today will be just as awesome! My summer is gonna be soooo badass!!

Person 1's Post: Wow it's like a Facebook summer "one-upping" convention.
