Sideburns which have massively overgrown and have started to twist and turn instead of growing straight down.

Due to the twisting and turning manner it can be compared to the Nurburgring race track, which apparantly has over 150 turns and twists.

Nurburns usually demonstrate a persons lack of care towards the way he looks, especially in the hair department.
