to be socially "terminated" by DG (aka Diamond Girl). Can be an act of rejection, insult, public embarrasment and/or ultimately; the degradation of one's ego, social status or self esteem. Being DGnated is also a form of having your "character" assassainated.
I was on myspace and DG told this dude to jump off! She totally DGnated him!
