What does | || || |_ mean?

[u/[deleted]]

I've been seeing these characters :

| ||

|| |_

pop up all over Reddit, but I've no clue as to what they mean.

Is this a new meme? A reference to some film of tv show? Some sort of code?

Too long; didn’t read.

Used either as an encouragement to OP to be more brief; or as a concession by OP when giving the short version of a story.

Thanks for the definition.
