Music Horn

Someone who listens to music but doesn’t understand the language/doesn’t know what the singer(s) is saying.

They also believe they can instantly learn a language just by listening to a single song.

Boy- yo what’s up with Cassandra??
Girl- I don’t know? Ever since she started listening to BTS she thinks she’s Korean or something. She doesn’t even know what they’re saying!
Boy- Wow so she’s a Music Horn?
Girl- I guess so!
