Editor's Note: Not to be confused with This is Snek.
Snek refers to images of snakes with interior monologue captioning applied. The captions often use a form of English that omits prepositions and/or spells words incorrectly; in addition, the word "heck" is often substituted for profanity.
The word snek derives from This Is Snek, the popularity of which led to an entire subreddit, /r/snek, devoted to images of snakes with and without the additional interior monologue captioning. The earliest known example including interior monologue captioning (below) was posted to the Facebook community "Snek" on October 16th, 2015. It obtained over 100 likes and 20 shares in 5 months.
