Yag is a way a person presents them selves. It can be abosulty anyone, but mostly targets white males/females around the age of 12-38. Majority if yag peolple are way to pale. A typical yag girl may own a shirt that says "Hottie" or "Cutie" across the front, or over/undersized sweatpants that have it printed across the anal area- when in fact, she is no wear near a hottie or cutie. Shes quite the opposite. Now a typically very yag boy might have blonde frosted tips on his hair, and trys to spike up the front with too much gel. or does not wash his hair. maybe owns a baggy button up shirt with flames on it, or pokemon. also maybe a black winter hat that he wears year round, with a crappy band printed on it. or maybe one of those necklaces with metel balls all coneccted together?. Now, people are able to "grow" out of yag, and leave it behind. but others....may god be with them.

Yag is a mix of Geto/whitetrash/muffin tops/pimples/frosted tips/bad taste in music/dirty/greasy/goth/horrible style/diarrhea face/hot mess/a big bucket of ugly/unpropperly fitted clothes/ and nasty.

It is gay backwards.
But it really has nothing to do with being gay.
It can mean that something looks crap or not good or someones not being very nice.
"Your so yag!"
"This skirt looks yag dont it?"
