Tim Patch, commonly known by his professional stage name "Pricasso", is a United Kingdom born Australian artist who is known for using his penis to paint. His major works are portraits, landscapes and female nudes.

In 1977, he migrated from the United Kingdom to Australia where he exhibited woodcarvings and other artworks in art galleries. In 1984 Patch established Hellfire Pottery with his sister, which produced various pottery and ceramic works. In 2002, Patch began work on building a Gaudí-style house and art gallery, and during this same period he began working as a portrait and caricature artist in markets in Queensland.

Patch first conceived of the idea of Painting with his Penis in 2005. Inspired after watching Puppetry of the Penis (Puppetry of the Penis is a comedic live performance-art show featuring a series of genital contortions). His first attempt at genital art was when he drew a smiley face in the back of a urinal with his penis and then decided to attempt it at home using paint. After telling a friend of his work, she dared him to paint at a 2005 New Year's Eve party. In 2006, Patch chose the name of "Pricasso" – a mixture of the word "prick" (a slang for penis) and "Picasso"

 Due to normal paint containing lime, which erodes the skin, Pricasso makes his own water-based paints. Before he begins painting he also covers his penis and buttocks in Vaseline in order to work for several hours without causing irritation to his skin.

Expectedly, art galleries showed little interest in his paintings, Which led Pricasso to became a regular attraction at Sexpo exhibitions around the world, where he paints portraits for attendees. He made his North American debut at the 2011 Miami Xposed Expo, and signed an agreement to appear exclusively at future Xposed Expo events.

Pricasso claims he has painted for various celebrities and celebrity parties, under the agreement to not publicize their events. Charlie Murphy was one celebrity who Pricasso noted as approving. Amongst the celebrities he said he painted portraits of are Hugh Hefner, John Howard, Kim Beazley, George W. Bush, Robert Mugabe, Barack Obama, Jacob Zuma, Queen Elizabeth II, Kevin Rudd, Tony Blair, and Luiz Inácio Lula da Silva.

In 2010, Pricasso appeared on the 4th season of German TV talent show Das Supertalent. After painting a female portrait on the stage, A female judge, Sylvie van der Vaart voted down the performance, but he progressed to the next round due to the support of the two male judges.

In the lead-up to the 2008 Sexpo in Cape Town, Pricasso published a video online showing him creating a painting of then-Mayor of Cape Town Helen Zille. Although he stated the painting was not meant to insult or embarrass Zille. On hearing of Pricasso's painting, Zille stated "This is a free country. A free society throws up these kinds of people, who exercise their freedom in unusual ways. And if this is how he wants to do it, I must accept his constitutional right to do so." Zille further commented that Pricasso "achieved a good likeness and I can't imagine how he painted it without brushes or conventional equipment."

In November 2011, Pricasso participated in a sexpo show. The nature of his technique caused other participants of the event to object to his participation, with one member resigning in protest. Pricasso responded to criticism by saying, "I think I'm just as good as anyone with a brush and I'm probably a lot quicker ... They can complain if they want to but other people love it."
