go-backs 

Items that have not been paid for and are still sellable, but for some reason are not in their correct spot on the shelf (or on the shelf at all).
If a person decides that they do not wish to purchase an item, from that instant forward it is considered a go-back until it sucessfully goes back.

"Is there something wrong with these cans tuna?"
"No, they're just go-backs."

Go-Backs 

At Whole Foods Market, items that customers decide they no longer want at checkout are placed to the side and declared as go-backs. These "go-backs" are taken by another employee and returned to their designated spot.

Whole Foods Employee 1: Aye, Big Dawg, can you take these go-backs?
Whole Foods Employee 2: Gotchu Big Dawg.

once you go black you'll never go back 

This statement derives from the general relativity theory published by Albert Einstein in 1915. It refers about the event in which an accelerated body crosses the spacetime boundary of a black hole known as the "event horizon". Beyond this boundary or "point of no return" the gravitational pull becomes so great as to make escape impossible and thus "you'll never go back".

"If a black hole is an oyster then the singularity is the pearl inside. The gravity is so strong it’s always hidden in darkness, beyond the horizon. That’s why we call it a black hole, once you go black you'll never go back."

Go back to the valley

A jocular, non-serious way of telling someone that they are sucking at something (usually surfing or skateboarding or some such activity). The expression originated among Los Angeles area surfers who would try to intimidate surfers from farther inland (usually the San Fernando Valley) into not surfing at “their” break. Locals could tell a “Val” because people from the valley usually weren’t very good (not having access to the beach as easy as coast residents). Hence the expression becoming synonymous with “you suck.” Was popularized as a catch phrase by several bad Hollywood surf movies (eg Point Break).

Dude 1 tries to kickflip off a curb and falls on his face.
Dude2: Hahaha, go back to the valley.

Go back 

A phrase common on various imageboards, especially the Chan boards.
The phrase is used to imply that someone is simply a tourist from Reddit-- which the Chan boards specifically despise-- and therefore must "go back" as they are not a part of this community.
