The whole point of using slang words is to be trendy, a member of the cool group that knows the latest word usage. These word usages may arise from anywhere, but they don't become trendy until a critical mass of the group, say, teenagers or influencers, use them. And considering how long these terms have been around, it could take a hundred years to reach that critical mass, or more likely, they were resurrected from a more ancient time.
For example, the word "fly" can mean an insect or the act of moving through the sky. But as a slang term meaning fashionable or stylish, you probably didn't hear it much until the 1980s. But it was used in exactly that way to describe a petticoat in a book written in 1753! The list distinguishes the slang term "high" from its normal meaning of elevated, which confused me for a second, because the word "elevated" is now a term used to get around TikTok censorship. But "high" meaning intoxicated by drugs, came into wide use in the 1930s to distinguish it from bring drunk on alcohol. But the term "high" was used for alcohol intoxication going back to 1607.
