* A slang term: It could be a slang word used in a specific region or community. Without more context, it's impossible to know what it might mean.
* A misspelling: It might be a misspelling of a real word. Do you mean something like "drafty" or "drippy"?
* A made-up word: Someone may have made up the word for a particular purpose.
To get a better understanding of what "driggy" might mean, please provide more context! For example:
* Where did you hear this word? (online, in conversation, in a book, etc.)
* What was the context? What was the speaker talking about?
With more information, I can try to help you figure out what it means.
