Original Graffitio Artist. An outstanding member of the Graffitio community. OGA members are long time users of Graffitio that fight the noble cause of eliminating users that do not contribute to the well being of the community. This includes eliminating users that claim to be OGA, while they are not. Many users want to join OGA but cannot due to the fact that the group is no longer accepting applications. OGA was started by two members in July of 2008 to battle the "Sexy Seven." (Initially, OGA was a group against groups) The war went on for a couple of weeks and OGA emerged victorious. During the battle, the leaders noticed a few other users that joined in to help with the elimination process. They were quickly added to the group. These few leet users have joined forces and are now known as OGA. Many people have tried to thwart the efforts of OGA and have failed miserably.

An actual crackhead. He doesn't do anything else except smoke and eat. almost a hundred percent of the time he is high off his ass in some other dimension, he'd do anything to get high as fuck. If you are called an OGA you are most likely never sober.

Stands for "Oh, good alligator". When one brings an alligator somewhere and it is very good. This phrase is what the other person would say in response. Only, they are just kind of surprised, hence the "oh".

(Original Graffitio User)
OGA refers to a group of four people on Graffitio who think they are better than everyone else and cut people who should truly be OGA out because they do not like them or have nothing better to do. OGA is now basically a group of people who have nothing better to do than exclude people from a group and feel special about themselves because they put themselves into a group that exists on an iPhone app.
K.R.F.C., Frantiic, Alk, and Steakpak must feel so good that they are in their fake little group and they can call themselves OGA.
