Boo. From chambers English dictionary, often considered the benchmark of dictionaries:
moot verb (mooted, mooting) 1 to suggest; to bring something up for discussion. 2 intrans to dispute or plead, especially as a form of academic exercise. adj (mooter, mootest) open to argument; debatable • a moot point. noun 1 historical in Anglo-Saxon England: a court or administrative assembly.
I think your source maybe from across the pond.
