Hehe. This happened to me on Sunday. It wasn't so much a word or sentence but more like a simian yell of "aaahhhaaaaaaayyy" which I assume was meant to mock my uphill endeavours. It gave me little satisfaction as I started catching up with them again on an immediate downhill section as they were stuck behind a nervous Sunday driver. I could tell they wanted to get away because their brake lights were coming on and off constantly as they tried to nudge the aforementioned Sunday driver on a bit faster. I hope they could read my lips in their rear view mirror because they eventually got away. I don't know what I would have done if I had pulled level with them anyway but it took my mind off my sore legs for a little while anyway (first time out this year after the winter).
