It's a copy and pasted block of text usually posted on a message board to troll newer users and as an inside joke between older users. Copypasta can usually be found posted in a discussion about any subject, and will usually be intended to draw out newer users into responding negatively to it, much to the amusement of more veteran users.
Copypasta might have started out as a real post somewhere, but people might have found the story so stupid or amusing that they post the exact thing years later to mess with people. It's much like a group of friends getting together to mock what another person said in the past and laughing about it.

My name is John, and I hate every single one of you. All of you are fat, retarded, no-lifes who spend every second of their day looking at stupid ass pictures"
Hey, I'll kick your ass for talking like that
"lol, look at this guy replying to copypasta"
"Hanging Chad" became popularized from the 2000 presidential race between George W. Bush and Al Gore.
A "chad" is the fragments of paper left over when you punch a hole in a card. Voters in Florida at the time used Votomatic style punched card ballots. So a "hanging chad" is when you punch a hole in the card, and it doesn't punch the whole way leaving a little piece dangling. A "pregnant chad" is when you attempt to punch a hole, but it just leaves a bulge and doesn't actually punch through.
The controversy came about when "hanging chads" and "pregnant chads" weren't counted by the machine. People's votes weren't counted.
Imagine if you take those tests where you have to fill out the circle completely with a number 2 pencil. But you didn't totally fill the circle out and your answer was marked wrong.
I tried to vote for my favorite guy, but it wasn't counted because I didn't punch the card the whole way through. I left a hanging chad.
Copy and pasted spooky short-stories made famous by 4chan's /x/ board. The term derives from "copypasta".
The stories aren't really copy and pasted anymore, but rather they are screenshots of the post so they can be shared and saved as an image rather than a huge block of text.
Can anyone post that creepypasta about the ghost dog in the hospital?
