Prank

A prank is defined as "acting like a clown or buffoon" or "dressing showily", or alternatively, "a ludicrous or grotesque act done for fun and amusement"[1]. Pranks can take the forms of practical jokes, hoaxes, or even petty criminal activity, such as the theft of traffic cones.[2]

In recent years, the term "pranking" has also come to mean the ringing of a mobile telephone and hanging up before it is answered, to alert the mobile phone's user without having to pay a network connection charge.
