Overview
The Dancing Hot Dog is the name often used to refer to a character and an Internet meme that originated in 2017, after the Snapchat mobile app released an augmented reality camera lens that includes an animated rendering of a dancing anthropomorphic hot dog.
Release and lens description
Snapchat often releases lenses and filters for its users to use; like the app's other lenses, the dancing hot dog is found by opening the in-app camera and tapping the screen until the lenses appear. The hot dog can be made larger or smaller, and it can also be moved around the screen, including when users record video. While many lenses use a phone's front-facing camera, the hot dog lens requires users to switch to their rear-facing camera.
The lens uses augmented reality (AR) technology to display a 3-D rendering of an anthropomorphic hot dog. The hot dog is shown in a bun, wearing headphones and enjoying music. By tracking real-world geometry, the hot dog will affix itself to in-frame real world objects and move along with them.
The song used in the lens is licensed by Jingle Punks Music, and is titled "Cool Nights-JP" by the artist Hint of Mint.
