An Internet meme ( ) is an activity, concept, catchphrase or piece of media which spreads, often as mimicry or for humorous purposes, from person to person via the Internet.
 An Internet meme may also take the form of an image (typically an image macro), hyperlink, video, website, or hashtag.
 It may be just a word or phrase, sometimes including an intentional misspelling.
 These small movements tend to spread from person to person via social networks, blogs, direct email, or news sources.
 They may relate to various existing Internet cultures or subcultures, often created or spread on various websites, or by Usenet boards and other such early-internet communications facilities.
 Fads and sensations tend to grow rapidly on the Internet, because the instant communication facilitates word-of-mouth transmission.
 Some examples include posting a photo of people lying down in public places (called "planking") and uploading a short video of people dancing to the Harlem Shake.
Krampus, the "Christmas Devil" of Austrian and Bavarian folklore, has entered the popular culture of North America; Christian Jacobs notes that "thanks to the Internet and YouTube [Krampus] is now very much on America's Christmas radar".
 Tanya Basu interprets this as part of a "growing movement of anti-Christmas celebrations": a "bah, humbug" rejection of – or novel alternative to – mainstream festivities.
 Brian Joines of Image Comics suspects that the reason Krampus (specifically, as well as dark aspects of Christmas in general) has not been historically popularized in America is a social artifact resulting from "the nature of how we view Christmas in this country, both as a big day for kids and as the birth of a big religious figurehead".
 In some North American depictions, Krampus is an antihero who seeks to prevent children from becoming spoiled by rampant consumerism flowing from the economics of Christmas.
Unexpected John Cena, also known as simply Unexpected Cena or And His Name is John Cena, refers to an Internet meme and a form of trolling involving videos that first garnered popularity on video-sharing services such as Vine and YouTube in the summer of 2015.

 and his theme song "The Time Is Now", often played loudly.
 The meme was very well received by journalists and Cena himself.
Netflix and chill is an internet slang term used as an invitation to watch Netflix together, and is also often used as a euphemism for sex, either between partners or casually as a "booty call".

 Much like "selfie", use of the term has now spread beyond the internet and into general common use.
Vaporwave is a microgenre of electronic music and an Internet meme that emerged in the early 2010s.
