shoplifter

Shoplifting is the theft of goods from a retail establishment during business hours. The terms shoplifting and shoplifter are not usually defined in law, and generally fall under larceny. In the retail industry, the word shrinkage is used to refer to merchandise often lost by shoplifting. The term five-finger discount is a euphemism for shoplifting, humorously referencing stolen items taken "at no cost" with the five fingers.
