The meme tricks the audience into seeing the computer-animated gnome – called Noggin Clontith – midst of watching something totally different.
Being out of context is a key element for this meme in order to work.
In 2018 a British website under the domain name NogginClontith.co.uk was launched, with the aim to tell the story of Noggin Clontith, the gnome.
A YouTube video was uploaded in 2010 by the website’s developers for marketing purposes.
The video featured Noggin Clontith looking at the viewer and screaming “you’ve been gnomed!”
The meme started to spread on Reddit in 2015, after user Rolfy posted the video on /r/DeepIntoYoutube.
After it, copypastas were created and I’m a gnome eventually made it to the Wiki page called Trollpasta.
In 2018, the phrase “gnomed” was given an article on Urban Dictionary.
