Toothpasting refers to a surreal internet phenomenon, most famously associated with the 'Shitting Toothpaste' image featuring a CGI toothpaste tube (often nicknamed Jonathan the Husky) defecating a glob of toothpaste onto a brush. While the term toothpasting historically referred to a 2010-era hoax about getting high from toothpaste, it evolved into a pillar of post-ironic meme culture. In modern usage, it is frequently used as a bait-and-switch or a non-sequitur punchline to replace more serious or predictable meme formats. Its popularity stems from its utter absurdity and the jarring nature of the 3D rendered character, making it a favorite for shitposters across Reddit, Discord, and Twitter.
