the size of a plug
not a verb. you can not gauge.
you can stretch a piercing you can not gauge it. it would be like saying "I'm going to large" its what Sizes are referred to. NOT a verb.
the bigger the number the smaller the hole. 18ga is a standered ear piercing size.. when the numbers get smaller ex, 16, 14, 12... it means the hole is bigger.
i have a 12 gauge piercing
