noun | fawrk
A fork is like when you and your best friend have a falling out and stop talking to each other, so you start hanging out with different groups of people - it's when a blockchain splits into two separate chains, usually because of a disagreement over the rules or a change in the code. It's like a divorce, but instead of fighting over who gets the dog, you're fighting over who gets the Bitcoin.
Example
"When Bitcoin Cash forked from Bitcoin, it was like watching your parents get divorced - everyone was picking sides and slinging mud at each other on Reddit. I just wanted my coins to moon, but instead I got caught in the middle of a nerd slap fight."
"Hard forks are like the ultimate rage quit - when you can't get your way, you just take your ball and go home. Except instead of a ball, it's a multi-billion dollar cryptocurrency, and instead of going home, you're starting your own blockchain with blackjack and hookers."
