Were you a live, sentient teenager in the 1990s? Then you probably remember JNCO jeans, those ultra-baggy denim pants with the 23-inch cuffs that flew off the racks at Hot Topic and were a hot topic (oh!) among disapproving adults.

On this installment of Throwback, we chart the rise of JNCOs and their status as an immigrant success story, explore this cautionary tale of teen fashion fads, and tackle some counterfeit controversy. Watch Mental Floss Editor-in-Chief Erin McCarthy break it all down and reveal, at long last, what JNCO actually stands for.
