If I recall (this being some time ago), it was the height of the period in which many of us enjoyed trolling conservatism, which largely consisted, then and now, of flamewars about gay marriage and abortion. Accordingly, someone came up with the brilliant idea of making a post with as few words as possible that would cause conservatives to lose their shit and have a 300-comment flamewar.

After some discussion, someone (I forget who) whittled the hypothetical post down to a single word: GAYBORTION.

When it came time to name the comic, I took a poll of all the various names I liked. "Gaybortion!" was actually tied with "That's Not Funny, My Friend Died That Way," but since my friend had just died, I went with "Gaybortion!"
