Day One: Garry's Incident 

A crappy survival game that became infamous for the developers using the Streisand effect silence TotalBiscuit's negative review on YouTube. His response video delivered more criticism to the developers. The developers also got accused of astroturfing the game's score on Metacritic.

Dude, don't review Day One: Garry's Incident because you could get Streisanded by the developers.

Macy's One Day Sale.

Definition 1: An above average looking male/female percieved as a 9 or 10, who couples up with a below average looking male/female, percieved as a 4 or a 5.

Definition 2: An analogy to explain how an unattractive person couples up with an attractive person. The unattractive person usually "shops" and "buys" his/her boyfriend/girlfriend at Walmart, but happens to get lucky and hit the Macy's one day sale.

Mark: Wow,,,,how did Fat Amy hook up with Johnny Football?
Kim: I have no idea.
Mark and Kim (in unison): "Macy's One Day Sale."
