What is "puroslam"

PuroSlam is the only nationally certified poetry slam operating in San Antonio, Texas, USA. Started in 1999 by Benjamin Ortiz, PuroSlam has earned a national reputation as one of the toughest, roughest, rowdiest poetry slams in the United States, bringing the exciting world of performance poetry to South Texas on a weekly basis. “I’m excited about San Antonio,” says Boston poet Dawn Gabriel in a 2006 article in the San Antonio Current, “because they have a reputation for being the meanest Slam poets around.”
