Happy Slapping is a 2011 Canadian drama film about disaffected youths, teen angst and bullying.

Its title is derived from the "happy slapping" fad which began in Britain where teens assault strangers on the street, film the encounters on their smartphones and circulate them on mobile phones or post them on user-generated websites.

[2][3] Five suburban youths embark on a night of violence in the city, attacking unsuspecting victims while recording the assaults on smartphones.

They seek out fame by creating an evening so shocking that their camera phone footage will turn them into instant Internet celebrities.

After they are rivaled by another gang and intimidated by their online idol, they are forced to take their mischief up a notch if they want to make a name for themselves.
