The screenshots for the image macro series come from the 2011 roleplaying videogame, The Elder Scrolls V: Skyrim.
In the game, players have several skills they can choose from to level them up, which include sneaking, speech, one handed as well as illusion.
The first meme that involved a screenshot from the Skyrim skill tree was uploaded to Reddit by Autistic_Spinning on June 18th, 2017.
Following June, 2017, memes like “sneak 100” started flooding the internet, photoshopped on to screenshots of chat conversations, news articles as well as game screenshots.
“Sneak 100” was first defined on Urban Dictionary in 2019.
