Demico Darnell Slack, better known as Dizzi Slick, or Lil Traphouse, is an American rapper from Seattle, Washington. He is a member of rap collective Underworld Dust Funk and a former member of Thraxxhouse.

In April 2017, he was arrested in his hometown of Seattle for attempted murder after a cocaine deal gone wrong months prior in California. After two years of fighting the case with a potential 39 year to a life sentence, he was given a plea deal of 10 years (reduced to six after two years served and two more for good behavior) and is set to be released sometime in 2025.
