Scoop Jackson of ESPN has come up with his NBAipedia and Gilbert Arenas has no less than 5 entries where he is mentioned in it:

Gilbert Jay Arenas, EA Sports, GAZO, Undrcrwn, and Unrestricted Free Agent.

Some of the more interesting comments:

Under Gilbert Jay Arenas:

Referred to in some NBA circles as “Gnarls Barkley” because his behavior sometimes matches the name of that group’s Grammy-nominated song.

Under GAZO:

The alter ego of Gilbert Arenas. Part Stewie (“Family Guy”), part Huey (“Boondocks”). Proves that Arenas is either brilliant or insane.

and under Unrestricted Free Agent:

(see Arenas, Gilbert)

I’m sure Gilbert will come up with a few more catch phrases this year that will make it to the NBAipedia.
