Acronym junction, what's your function?

I suppose you could see MILF in an AAR. But the mind boggles.

If you don't allow the F word, then you shouldn't allow a hidden version of it. If there is room for bending that rule because of context, then it isn't a proper rule.

You might show leniency in applying the rule, but "no use of swear words except when not directed at any one individual, but rather at the poster's own inability to find an alternative phrase" really muddies the water for when you have to apply that rule.

Oh, and if you use the daisy smiley, then not everyone knows what you meant to say. In particular, small children don't know. So it does work better than simply saying it.
