Rigga

A rigga is an oil rig. This slang is often used to refer to an oil rig by the crew of the rig, as a form of disrespect to the rig. This choice of language shows familiarity with the oil rig and a distaste for the proceedings that continue within.

Man, I can't stand being on this rigga. I just want to go home.
