noun | fi·peh·ning
The flippening is like when your little brother finally beats you at a video game after years of trying - it's the hypothetical moment when Ethereum overtakes Bitcoin in market cap and becomes the dominant cryptocurrency. It's like the nerd finally getting revenge on the jock who bullied him in high school.
Example
"I've been waiting for the flippening ever since I bought my first ETH back in 2017. Every time it gets close, I start shopping for Lambos on eBay. But then Bitcoin pulls some bullshit and pumps to new highs, leaving me with nothing but a pile of shitcoins and broken dreams."
"The flippening is like the crypto equivalent of the rapture - everyone's been predicting it for years, but it never actually happens. It's like waiting for your dad to come back from the store with those cigarettes he went out for 10 years ago - at some point, you just gotta accept that it's never gonna happen and move on with your life."
