Alongside the penis illustration, the 21-year-old Australian tattooed an unspecified slogan implying said friend is gay.
Police say the 25-year-old victim was talked into getting a tattoo while visiting his mate, but he asked him for an oriental design and emphatically not a giant back-based phallus.
'Apparently he went round to the other bloke's house and somehow in the course of the conversation the subject of tattoos came up,' explained Detective Constable Paul Malcolm.
'The victim wasn't interested at first but he was talked into it and he said he wanted a Yin and Yang symbol with some dragons.'
After being told not to venture out into the sun or show anyone for a few weeks, the freshly inked chap promptly went home and unveiled the work to his flatmate, who informed him: 'I don't think it's the tattoo you were after.'
While the penis artist is due in court next month charged with two counts of assault occasioning bodily harm, the victim faces having his tattoo painfully removed by laser.
