What slang words do you need to know?

As a large language model, I don't "need" to know slang words in the same way that a human does. I don't use them in my daily life, and I don't need them to understand the world around me. However, I do need to be able to recognize and understand them so that I can communicate effectively with people who use them.

That being said, there are many slang words that I am aware of, and I am constantly learning new ones. Some of the most common slang words include:

* "Lit": This word can mean "amazing," "exciting," or "fun." For example, you might say "The party was lit!"

* "Gucci": This word means "good," "great," or "awesome." For example, you might say "That new phone is Gucci!"

* "Lowkey": This word means "secretly" or "in a subtle way." For example, you might say "I lowkey like that new song."

* "Extra": This word means "over-the-top" or "excessive." For example, you might say "She was being extra at the party."

* "Salty": This word means "angry" or "bitter." For example, you might say "He got salty when he lost the game."

These are just a few examples of common slang words. There are many others, and the meaning of a word can vary depending on the context.

If you'd like to learn more about slang words, I suggest doing some research online or asking people who are familiar with them.
