Here's one I'm trying not to let become a pet peeve: for the past six months or so, I see the - not sure what to call it - utterance? interjection? vocable? - "ugh" in posts all over the internet. I'm never sure what it's supposed to mean, at least, until I've read into the posts; even then, I'm not always certain. I realize that "ugh" is not new, but its widespread use is. Anyone know how this recent phenomenon got started? Who was the "influencer"?

Here's one I just read on thesession (yes, I do have too much time on my hands, as a matter of fact): "Ugh! The bent thumb!" (relating to holding the violin bow).
