mush (mouche/marche) retry from OED citations

[janilta]

Alan, Mike,

Mmmm. Whereas 'mouche' is indeed standard French for 'a fly', I don't
think there is any 'moucher' in the meaning 'to fly' (at least not in
standard French), even if it sounds logical. The common meanings for
'moucher' are 'to blow (one's nose)' and its slang counterpart 'to snub
so'. There is also 'to cut off the burnt part of st'.
We're far from the dogs and the prairie here I'm afraid.

Cheers, Yann.
