Abbreviation for the term, 'Oh Our God,' used rather than, 'Oh My God.' Some people (mostly super religious ones) are offended that you would think that God "belongs" to you, so now if you ever meet a crazy religious person, make sure you make it seem as if you "share" God.

Based on the pursuit of personal info by fellow internet users beyond what is normally acceptable by a user under the handle "Oogie". To "Oog" indicates any act beyond what is socially acceptable, or any act closely resembling stalking, that involves stockpiling information on other users in an effort to gain data on their personal life.
"I oogied some info and now have your personal home telephone number, your daily work hours, how many kids you have, what schools they attend, where you work, and how much you got paid last week...you know, the basics."
