Burglars and pirates handle a lot of loot — otherwise known as stolen money or goods.
One bank robber might say to the other, "You watch the customers! I'm going after the loot!" Loot most often means money, especially the kind of money you didn't get legally. Loot is right up there with booty and swag in the family of words for stolen or pillaged things. When used as a verb, loot refers to the act of stealing, like when an angry mob loots the local grocery store during a riot.
