It is an idiom very common in Australia. (It may not be well known in the rest of the English-speaking world.) It means to figuratively flap one's hands around in the air while skipping over technical details or complications. For example, we often talk about "hand-wavy estimates" for how long a job will take: "my hand-wavy estimate is it will take two days" is little better than a guess. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
