From The Stargate Omnipedia
Name given to Daniel Jackson after he descended back to human form, and was placed by the Ancients on the planet Vis Uban. It translates to "naked one" in the language of the nomadic tribe that found him there. Because an amnesiac Jackson did not remember who he was, the villagers knew of nothing better to call him.
Fallen - Daniel descends naked, earning him the name "Arrom."
