I've been to Jamaica a couple of times and I swear I've heard people use the term "dirty shirt" as a verb. My uncle Ken who lived in Negril for years, used the term too.
What it means. When someone dirty shirts you, it's as if they did something that left a stain on your shirt, something obvious and not nice that everyone can see.
Example: When my cousin sell me bad ganja he dirty shirt me man.
But when I searched for the term on Google, or asked ChatGPT, they offered weird and wrong ideas for what the term means.
I checked in with my friend Dave Jacobs about this, he has the same understanding of what the term means, but he couldn't find our definition anywhere on the web either.
At least now the correct definition will show up here on my blog.
I find I'm starting to write like ChatGPT. Go figure. 😄
