Define Spite Monkey Attack Meaning

This is an action that usually takes place on Spite Monkey Sunday, some little prat decides that they can best get their self-aggrandising definition accepted by making multiple submissions. They then decide to try to improve their chances by voting against any other definition that has been submitted, a typical demonstration of the spite monkey mentality. The end result of their self-centred, immature nastiness is to effectively bring Urban Dictionary to a standstill.
