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.
Correct Use: "I want to buy some 4 gauge plugs." or "This piece of jewelry is 12 Gauge 5/8" tongue labret."
"What size are your plugs?" or "What size jewelry are you wearing in your ears?" are effective ways of inquiring about someone's stretched earlobe piercings without making yourself look like an idiot. Walking into a piercing studio and saying "I want some new gauges," is also incorrect. Try saying "I'm looking for some 4 gauge plugs." or playing it even safer, "I'm looking for new earrings."
Also the device used for measuring.
v. To measure or estimate. Basically, it doesn't mean to stretch.
"I'm going to buy more gauges for my ears!"
"I gauged my ears to 00."
"I stretched my lobes to 4g."
"I used a gauge to see what size my jewellery was."
"I need to gauge my plugs because I forgot what size they are."
