OGX is a relationship term and is an abbreviation for “original gangster ex-partner”.
Though a person may have many relationships that they have been in, and have many ex partners, the OGX is what one calls the substantial relationship in their life, and one considers this ex the “ex that matters.”
Sometimes this classification of a ex is due to the duration of the relationship (ie how long they were together), status of the relationship (ie first long-term relationship) or how strong the emotional investment was to them.

You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine. Do you know that the orange lodges agitated for repeal of the union twenty years before O’Connel did or before the prelates of your communion denounced him as a demagogue? You fenians forget some things. (James Joyce, Ulysses. Penguin Books,1992. p. 38)
