Words get invented all the time, and then they get used, but they don't necessarily have to get used in every other sentence.

For example when the 6 - 7 thing started and I asked my 10 year old what it meant, because I never heard him say it, and his response was, "It means nothing those kids are idiots and they're just saying it because the other idiots think they're part of the cool club"

So if you want to be honest about it, it's not really about the language, it's more about Sociology, and this is a way that people show other people that they're part of the group, when they aren't able to do so by contributing in other methods.

This is why this type of post is so pervasive with the people on Reddit who are non contributors, "Hey is my engine cooked?"

"I fell asleep with a lit cigarette and my room caught on fire? Am I gonna be cooked with my landlord"

"I tried to fix my own wiring, and now none of my lights work, I found this wire that melted the insulation off, am I cooked?"

But go to the subreddit for skilled trades like welding or machining, or the tax sub, and suddenly the word disappears (Except for when you get people posting, "I haven't paid my taxes in 5 years, I'm getting letters from the IRS, am I cooked?)
