We're talking about blatant violation of the FARs.

Really? What is the technical definition of a "cloud"?

Yes, really. As far as definition is concerned, the OED will do for me. "Visible
condensed water vapour suspended in the atmosphere high over the general level
of the ground."

If I can see through it, is it a "cloud"?

Yep. It just has to be visible.

Is there a size parameter?

Nope.

I've searched and can't find a technical definition of an
"FAA cloud".

The FAA usually feels that they don't have to define commonly used English
words. Webster's or Oxford already does that job nicely.
