thanks everybody..you broadened my world (and set me wondering whether foot-up started as a putting-on-the-brakes signal)

I learned a made-up term to use in answer to "what kind of gathering do you all have?"
I learned about professional gas expulsion.
I learned about various abominations (thanks Eddie, my mother will want to post that at our local gathering spot)

You guys sure are handy to have around!
Take care,
M
