OHDI is an acronym for Out Here Doing It, often used on social media sites like twitter, facebook, instagram and vine with a hashtag, i.e. #OHDI, in order to let people know that you are stunting like it's a habit. The word gained prominence in early 2010 in Southern California, and is used often as a means of letting people know that you are out here really taking it to the concrete and getting your flares out.
