it's means A do-rag or du-rag is a scarf worn on the head after a hair treatment process Do-rags were originally founded as the headgear of poor African American women laborers and slaves in the 19th century. In the 1930s, during the Harlem Renaissance and Great Depression, the do-rag evolved into a hairstyle preserver. After the Black Power Movement in the late 1960s, the do-rag became a fashion statement among African Americans, worn by rappers, athletes and men of all ages. In the 2000s, wearing do-rags in public lost popularity in certain areas but maintained its popularity in others. However, because of rappers, such as A$AP Ferg and the return of waves as a hairstyle, they have now regained their status as a fashion among the African American community. Do-rags can also be apart and or observed by different religions. In 2001, the American National Football League banned its players from wearing do-rags and bandanas underneath their helmets. There are even universities that ban do-rags on campus. Motorcyclists wear do-rags, especially in US states with motorcycle helmet laws, to prevent "helmet hair" or "helmet head". The do-rags prevents sweat and sebum from causing an unpleasant smelling helmet, and also prevents sunburn when worn without a helmet.

Very interesting dialogue. Do-rag is a head scarf worn to protect one's hairstyle. Not sure how that term fits into the dialogue.
