A folder in which pictures of random people from "last weekend" are placed, alongside people who seem to be around a lot.
Can be used to secretly confirm a persons acceptance into the group as a kind of code-phrase.
Man 1: "Think she'll make it into the US folder?" *points at random girl*
Man 2: "Nah. Last weekend, Definitely."
