Booster

nounShop talkShop Slang

A professional shoplifter who steals retail goods in bulk to resell them on the black market.

In retail, loss prevention, and warehouse environments, this refers to organized thieves who target high-value, easily fenced merchandise. Unlike casual shoplifters, they operate systematically, often using foil-lined bags or coordinated distractions. Store security teams track their methods closely to prevent massive inventory shrinkage.
