Dwayne Mahorn (born 11 May 1981), better known by his stage name Durrty Goodz, is a British grime MC, rapper and songwriter from London.

He is known for his versatility across his tracks with a flow that fuses many styles, from dancehall to reggae to hip-hop and bashment, evoking artists as disparate as Ludacris, Kardinal Offishall and Pharoahe Monch.

[3] Mahorn's brother Crazy Titch was accused and later convicted of murdering 21-year-old Richard Holmes, and was sentenced to 30 years without parole.

He releases regular freestyles on his youtube channel "Durrty Goodz FM",[4] labelled Bar Codes.

Also in 2013, he was featured on M.S.G's mixtape Never Give Up, on "Krispy Kreme" with Logic, Last Resort, Sway, Mighty Moe and Big Frizzle and on "It's Alright" with DJ Ironik and AYO Beatz.

On 8 July 2016, he announced that he would be releasing a new EP titled Not Been Televised which was produced solely by YNR Productions rapper/producer Micall Parknsun.

Tru Thoughts announced that Goodz would release Hungry Belly which is a selection of grime standout tracks.

In 2017, Mahorn rebranded himself as "OG Rootz" and a collaborative EP with long-time rival Wiley was teased, but as of yet nothing has come to light.

In 2019, under this new alias, he released videos onto YouTube for the songs "Ackee & Rice",[5] "Scotch Bonnet",[6] "Frontline"[7] and "Babylondon".
