Kids nowadays like to use slang for anything. Older generations don’t know what it means either such as “bust-down” or “iced out”.
Bust-down means when you have a piece of jewelry that has a lot of diamonds and is very expensive that is your bust-down. As for being “iced out”, that means your jewelry has a lot of diamonds on it and is shiny.
“There are many ways to increase your fortune”; the millennial slang for that is to either “secure the bag” or “get the bread”.
There are many slang words for various words or phrases. There are so many that get started from a trend or kids say to sound cool. They can start because of a meme such as when a man said “what are those” to a police officer's shoes and it started a huge trend of people saying that.
It was referenced in the movie “Black Panther.” There are many slang words that are used every day by many people while texting such as “lol” there are many others. There are even words that are normal but mean something else such as “mad” which means to normal someone is angry in slang it means its crazy lit.
“Low-key” is another one it means that something is on the low or to keep it quiet. People say fire and they're not a fire it just means something is really cool.
