When the funk/rock 4 piece band Factotum take a song and butcher it until it is unrecognisable to the untrained ear, apart from the lyrics which mostly stay the same.
Factotum can factotumise any song from Daniel Orlick's 'Attitude' to Aretha Franklin's 'Respect'.
Music fan 1: "Hey, did you hear that version of Respect on the radio?"
Music fan 2: "Which one?"
Music fan 1: "The factotumised one."
Music fan 2: "That was Respect? It sounded nothing like it. Well, apart from the lyrics."
