the floor

Since Better Half and I both lived with each other's dialects for some time before meeting each other, there aren't too many times when our linguistic differences get us into trouble. But one thing that hasn't stopped confusing me is when he calls the ground outside the floor. For instance, we might be walking along the (BrE) pavement/(AmE) sidewalk and he'll say "Mind the poo on the floor there" or "Look at all the chewing gum on the floor!" (He's just come up with those two examples himself, reminding me of my mother's recurrent surprise at the 'uncleanliness' of England. Of course, my mother lives in a small town in a rural area in the US, so her comparisons to cities in England aren't really fair.)

Anyhow, BH's exclamations about things on the floor almost always knock me for a loop, because to me the floor is something inside a building. Of course, in AmE I can also talk about the forest floor, but I think of that as being a very speciali{s/z}ed usage; it doesn't just mean the ground in the forest, it means all the ferns and mosses and things that one finds on the ground in a forest. Similarly for the ocean floor--to me, it's about an ecosystem, not just a surface.

I've asked various BrE-speaking friends whether they use floor to mean ground, and their replies have been mixed. (But it also should be said that I usually don't think that asking people whether they say X is a very productive or accurate way of finding out if they say X. What we do when speaking is a largely subconscious process, and when we reflect on that process, all sorts of things, not least ideas about how we 'should' speak, get in the way.) Looking in the OED, I find that it lists the sense 'the ground' as obsolete, except in dialects.

Now, as a Saaff Lundun boy descended of a long line of South Londoners, I kind of doubt that BH is hanging on to some old ways that the OED compilers thought of as 'dialectal'. So, my hypothesis is that this usage has been re-introduced to the general language through cricket. (This would contribute to explaining why BH uses it more than most of my girlfriends.) As the OED notes, floor is the ground of a cricket ground--that is to say, the dirt/grass part of the cricket field (too many senses of ground in that last clause). So, the OED also lists to put a catch on the floor as a colloquial way to say 'to fail to hold a catch' in cricket.

I was reminded of the whole floor issue while watching the quiz celebrating Channel 4's 25th anniversary last night. (For certain reasons, I'm watching way too much television lately.) They showed a clip of a program(me) in which Derren Brown gets 'normal' people to hold up an armo(u)red bank car. And in that, in the out-of-doors, the robber demands that the bank guy get 'down on the floor' (i.e. on the street/road). You can see a clip from that (BrE) programme/(AmE) show here on YouTube, but to hear people saying floor, skip to about 7:24. Here, of course, there's the possibility that the speakers have been affected by seeing lots of dramati{s/z}ed robberies that take place inside banks, and so the thing that one says in that condition is Get down on the floor. But it still sounds really unnatural to me--I can't help but think that I'd say Get down on the ground. Next time I rob an armo(u)red vehicle, I'll have to have someone tape me.

So--can you refer to the surface of a road as the floor?
