The term is an interesting one, and it does seem to often have an edge to it. I think I prefer "dropping", though that term would probably bother some anyway. Regardless, I've not done it often, but I've done it a few times. Generally the other rider has been very new or only rides once a year, far more out of shape, and/or on a bike without many gears. There isn't much of a chance for an ego boost when I've done it. This is a good thing!
