"Jeep ducks" refers to the tradition of Jeep ducking, a kind gesture where Jeep owners leave rubber ducks on other Jeeps, often with a nice note, to spread joy and build community. Started in 2020 by a Canadian woman to share cheer during the pandemic, the "Duck Duck Jeep" trend has grown into a global phenomenon, with owners collecting numerous ducks on their vehicles.
“Cruise ducks” are rubber ducks that passengers hide throughout a cruise ship for others to find as part of a game of hide-and-seek, a trend that began in 2018. When a duck is found, the finder can either keep it or re-hide it. The activity, which is voluntary and not organized by cruise lines, has become very popular.
