Trick-or-treat

Trick-or-treat is a Halloween tradition in which children who dress up in costumes appear at people's doorsteps to demand a treat from their hosts. Rarely, if the person does not offer the child a treat, they will be rewarded with a "trick" visited upon them by either the child or by someone else.
