Someone who spends all their money on ugly, shitty jewelry and insists on wearing as much of it as possible.
April hated her jewelry junky roommate. You could hear the banging and clicking of her ugly necklaces, bracelets, anklets, and rings every time she moved around the house.
Annie was a pathetic jewelry junky. She’d parade around the office in 10 cheap gold chains and bracelets up to her elbows.
