It's like you're pretending the word is so repugnant to you that you don't want the full word dirtying up your comment history. It lies in the same vane as fake outrage and sarcasm.

I'm pretty sure people do this with contentious names or topics to avoid the people who are using it as a search term to engage in less than savory ways. People that follow them know what they mean, but people purely looking for people to get angry at don't see it in search.
