Capping stunt
A capping stunt or capping is a New Zealand university tradition of student pranks wherein students perpetrate hoaxes or practical jokes upon an unsuspecting population. They traditionally take place in May during graduation.
Capping stunts have a long tradition in New Zealand, and are a prominent event at and around campuses throughout the country, with many notable instances reaching national or local headlines.
The stunts commonly play on the accepted civil rules of the host city, with the local city councils or media as the target. The capping stunts that generate the most media exposure generally involve passive techniques such as letter writing; however, material pranks such as the suspension of inflatable genitals from university property are common.
