Teens told Business Insider that these are their most-used slang words.
Here's what they mean.
Lit: When something is very exciting or energetic — like a "lit" party.
Bet: "Bet" is usually a one-word agreement — sort of like "I bet you do." You can replace "Ok" with "bet."
Shook: Shocked or surprised. Can't believe what you're seeing.
Key: The more succinct sibling of "major key," key indicates something important or vital to one's success.
Slay: Succeeded in something amazing.
