That's ghetto (formerly: "ebonics") for SUBURBAN.
Also known as CHEVY SUBURBAN.
We were in tourists in DC for the ‘13 sequestration, I can’t recall exactly, but we were paying over $4.00/gal for gas...and it made my blood boil to see all the Suburbans triple parked around the US Capitol, idling...waiting for their congresscritter so they could drive them home.
Made my blood boil. Such waste.
In this instance, hilLIEry probably ran out of gin and tonic...and a new case had to be delivered post haste for her long weekend.
