the act of deliberately shagging a minger in order to get a bit of confidence and mojo happening. usually used as a last resort to get out of a slump or a drought. The power of the minger roll comes from realising that you are in fact better than the minger. Once you finish with the minger you then seek better prey.
commonly referenced by the adage 'you have to slay a few dragons before you get to the princess'
