From the Liverpool term 'wooly back'. Even though it was origanally an insult aimed at them, people from the Wirral have taken this word as their own. It is now used commonly by youths in certain Wirral schools to describe an idiot or fool. There is also the use of the 'wool chant', which is used in the same way but it is chanted by many people instead (a good chant needs infusiasm, and needs alot of experience. when done properly the chant ends up sounding like louds of people shouting 'wall', completely independantly,) Many people from the wirral have also started to describe themselves as wools, as a sign of how they are proud to be from the Wirral.
