A seemingly permanent sunglass-shaped tan line outlining one's optical region. Caused by dangerously high levels of ultraviolet exposure. Commonly found on the faces of bronze beach babes and metrosexual males.
Dude 1: What happened to your boy's face? Did he fall asleep at the beach?
Dude 2: Nah. He just picked up a new pair of permashades at the tanning salon.
Dude 1: He's so metro.
