I don't have an explanation for what you are seeing. I did a search of all our templates and javascripts and of the three terms you saw, only "emoticons" is used. The phrases "Text body" and "more emoticons" (case insensitive) are not used at all. If I had to guess, I would say that your browser is caching a javascript from another website that is being triggered somehow. But this is only a guess and possibly totally wrong. But, a good first step would be to clear your cache. Beyond that, I haven't heard any other reports of such behavior so, as far as I know, this is limited to you.
