Filmed in a comic book style, it shows a man in a hospital being offered a number of increasingly large penis sizes from "The Ross", "The Vernon" through to "The Moyles", before he ends up choosing the super-sized "The Moyles".
Following the operation, the man awakes and is delighted with the result. When an attractive and well-endowed female nurse enters his room, he becomes aroused, but finds his new extension is not as great as he thought.
The viral ends with the strapline "Enjoy your money. But don't over extend yourself". The final scene shows the man wincing as his super-sized organ is hit by a closing window.
Chris Delahunty, digital marketing manager at Virgin Money, said: "Virals are a fun, targeted way to get people thinking differently about their finances. Maverick has turned the concept of using money responsibly into a risque, but fitting viral designed to reach a large audience quickly and make them smile."
The "Don't Over-Extend Yourself" viral campaign and website was created and produced by Maverick.
Virgin Money has previously released viral movies and games, including the much-played for the World Cup.
In March, it unveiled a viral campaign featuring boss Sir Richard Branson enjoying a sex romp in a Jacuzzi, as part of the promotional activity for the launch of its mortgage service in Austrailia.
