To D.W.G.'s point about playing a sport or doing any activity without really knowing the "terms," it is definitely valid. I have engaged in plenty of activities where people less intense about it than me know more of the nomenclature. Bike riding is my example. I have been riding bikes (road and mountain) much of my life (I have done several road tours) but couldn't converse intelligently about it with a guy that works in a bike shop.
