A piece of trash, utter shit. This term is a variation of the phrase "hunka-hunka burning love" from the song "Burning Love" by the one and only Elvis Presley.
During the week of August 16 (Elvis death anniversary) a TV network had an "Elvis flick" about how his ghost haunts the city of Memphis and gives advice to some local residents. The TV guide said that the TV movie would make Elvis spin in his grave - don't waste your time, it's a hunka-hunka burning crud.
