When a , bitchy, rich entitled woman or teenage girl wears giant dark sunglasses and doesnt take them off when inside (especially when ordering at Starbucks). The sunglass lenses are enormous and cover half her face. The size of the sunglasses is directly proportional to the level of bitchiness. GSB for short. similar to rehab glasses.
Check out the blonde chick over there who cut in line at starbucks and is being rude to the barista. Shes still wearing those huge dark sunglasses! What a giant sunglass bitch.
