PR dialect Spanish? Is that why people who speak Spanish couldn’t understand Bad &Rotten Bunny?
I was with 2 native speakers (from Mexico and Argentina) - they said they understood about 10%-20%. Some of it was just him "rapping" badly on live TV, the rest, I was told, it was simply all PR slang and references relevant in Puerto Rico only.
Or Horrid Hare, as I call him.
