What does MCF mean in the subject line of a post?
MCF stands for “My Cat Fluffy”, and was initially coined as a complaint about posts on the personal trivia of listees. Most specifically posts about the lives, deaths, and so forth of listees’ cats, though posts on dogs, other pets, and minor events in the lives of listees themselves can also fall into the category. MCF, removed from its pejorative beginnings, has become a convenient list marker for posts which relate to personal matters in the lives of listees that other listees might prefer to skip. Its use is optional.
