A woman reportedly asked a tattooist to draw a Yin Yang symbol on her back only to discover he had instead created an image of a penis alongside the word “f***”.

An Austrian court heard the 21-year-old woman asked the man, who was a hobby tattooist, to draw the Chinese symbol onto her.

He reportedly said he was happy to do so, and designed a template for the design which he showed her, according to The Local.

But once he began applying the ink to her back, he apparently disregarded the template, and instead drew an impromptu phallic design and a swear word.

The woman reportedly only realised what he had done when she went home and looked at the tattoo in the mirror.

Appearing in court in the small city of St. Pölten, where the incident occurred, the man was asked by the judge why he had drawn the penis, to which he replied: “Just because.”

The man, who is also 21-years-old, faced a charge of bodily harm, along with several other charges, relating to burglary and violence.

He was sentenced to three-and-a-half years in jail and will be held in a facility for mentally ill offenders.

It is not the first time a tattooist has been given jail time for etching a penis in place of a Yin Yang on to an unsuspecting victim.
