This infamous act involves doing the traditional testy tuck, which is obviously placing your scrotum and penis between your legs.

However, the magic starts when you also nipple yourself, whilst your friends and/or relatives take incriminating photographs of you.

And voila - you've done The Sergeant Bilco

This act first came to notoriety in 2007 in a Magaluf hotel room. To fully recreate this filthy act, a sleezy, darkened hotel room makes for a perfect ambience.
