Precisely Jerry, you may as well conclude that it refers to feeding fish because of the similarity to "Munch".

Added to which the theory that the Celts "fled" anywhere to escape Saxons or anyone else has been discredited by genetical research. Data from the Human genome project indicates that there is a common racial / ethnic strain running from Ireland (ALL of it) across Wales, across all of Southern England to Essex and extending into Western France. The prick is mightier than the sword, and assimilation easier than extermination.
