The term refers to an action taken on by a hotel guest or a party guest.
1. When a hotel guest leaves the room and takes everything with them: soap, towels, amenities, ice bucket, pillows - anything specifically not bolted down or too heavy for one person to carry. A hotel guest that is given food and beverage amenities and takes them all is a good example.
2. When a party guest is invited to someone's house and takes with them a miniscule party favor. Then they begin to eat five plates of food that other guests brought and they take a to go box with them when they leave the party.
Hotel General Manager: "Let's go check out that VIP room that we had all of those special amenities sent to."
Rooms Division Manager: " I already did, the dude Browned us. I thought Room Service already took out the amenity tray, but even the plates got Browned."
