I've never actually heard this term before, but I think it's silly. Why assume a guy can/should be better than me? Why assume he can't? Gender has nothing to do with it.

On the ERock ride I did this weekend, on an uphill, I passed a tall, fit man on an uphill. Apparently he looked a little annoyed by it. Well, that's what happens on a big ride, buddy. Total riders that day was about 7500 between the different lengths.

At the same time, I usually ride with two guys. I constantly, routinely, lead and set the pace. If I drag behind, I usually can catch up and pass too. No one cares. We're all going to the same place.
