What it means
High-key is what you use when you're not even trying to play it cool. It means openly, obviously, or very much. If low-key is the quiet little side-eye confession, high-key is the full chest version. You high-key want the promotion, high-key miss your ex, high-key think that song absolutely slaps.
Usage examples
"I high-key need a holiday, I have been running on coffee for two weeks."
"She high-key loves that cheesy show but pretends it is on by accident."
"I'm high-key jealous you got tickets, mine sold out in like two seconds."
"He was high-key panicking before the interview but tried to act unfazed."
Where it comes from
High-key grew out of online slang as the opposite of low-key. Once low-key got big on Twitter, Tumblr, and everyday internet chat in the 2010s, people started using high-key for the same kind of confession but louder, less hidden, and with way less chill.
