A stupid term that Oprah heard from somebody else and plaguerized, and now everybody uses it as a buzz word. Generally used whenever ANYTHING happens in a woman's life other than driving the kids to soccer, getting a new minivan, or staying home and watching TV.
Woman 1: Hey look there is a sale at Wal-Mart!
Woman 2: Oh my god! This is a full circle moment for me.
Woman 1: What the fuck are you talking about? Are you retarded?
Woman 2: No. Oprah says it every second day whenever something happens to her.
Woman 1: Oh my God! Then this is a full circle moment for me too!
