A modern day pirate that is/was active post the release of the movie "Pirates Of The Carribean". This term was coined on Triple J, an Australian radio station, when it was decided that the word "pirate" conveys too much Pirates of the Carribean-ness.
"Did you hear about those Somalian pirates hijacking one of our ships?"

"yeah, those hydrogangstas are taking us all back to the age of "Pirates Of The Carribean".
