Internet memes introduced in the 1990s

"Hooked on a Feeling" is a 1968 pop song written by Mark James and originally performed by B.J. Thomas. Thomas's version featured the sound of the electric sitar, and reached No. 5 in 1969 on the Billboard Hot 100. It has been recorded by many other artists, including Blue Swede, whose version reached No. 1 in the United States in 1974. The Blue Swede version made singer Björn Skifs' "Ooga-Chaka-Ooga-Ooga" intro well known (and famous in Sweden at the time), although it had been used originally by British musician Jonathan King in his 1971 version of the song.

goatse.cx (GOHT-see-dot-see-EKS, "goat sex"), often spelled without the .cx top-level domain as Goatse, is an internet domain that originally housed an Internet shock site. Its front page featured a picture entitled hello.jpg, showing an image of a hunched-over naked man using both hands to stretch open his anus and expose his red rectum lit by the camera flash.

The More You Know is a series of public service announcements (PSAs) broadcast on the NBCUniversal family of networks in the United States and other locations, featuring educational messages. These PSAs are broadcast occasionally during NBC's network programming.

Mahir Çağrı (born 1962) is a Turkish individual who became an Internet celebrity in 1999. His picture-laden personal homepage, which exclaimed in broken English his love of the accordion, travel and women was visited by millions and spawned numerous fansites and parodies, one featured on Fox's MadTV (season 5, episode 20). He was also repeatedly parodied in 1999 on episodes of the Late Show with David Letterman wearing red Speedos and playing Ping Pong. Mahir was ranked #2 in CNET's Top 10 Web fads (July 15, 2005). The site was also included in PC World's "The 25 Worst Web Sites" list (September 15, 2006). Mahir claimed in various interviews that his personal webpage was hacked, with additions such as "I like sex" embedded into his webpage. The site was originally hosted on the now defunct XOOM web hosting service which advertised Mahir on their front page during the mania.

James Parry (born July 13, 1967), commonly known by his nickname and username Kibo , is a Usenetter known for his sense of humor, various surrealist net pranks, an absurdly long .signature, and a machine-assisted knack for "kibozing": joining any thread in which "kibo" was mentioned. His exploits have earned him a multitude of enthusiasts, who celebrate him as the head deity of the parody religion "Kibology", centered on the humor newsgroup alt.religion.kibology.

In slang, a troll is a person who posts deliberately offensive or provocative messages online (such as in social media, a newsgroup, a forum, a chat room, an online video game) or who performs similar behaviors in real life. The methods and motivations of trolls can range from benign to sadistic. These messages can be inflammatory, insincere, digressive, extraneous, or off-topic, and may have the intent of provoking others into displaying emotional responses, or manipulating others' perceptions, thus acting as a bully or a provocateur. The behavior is typically for the troll's amusement, or to achieve a specific result such as disrupting a rival's online activities or purposefully causing confusion or harm to other people. Trolling behaviors involve tactical aggression to incite emotional responses, which can adversely affect the target's well-being.

The Hampster Dance is one of the earliest examples of an Internet meme. In its original incarnation, the meme first surfaced as a web page in 1998. Created by Canadian art student Deidre LaCarte as a GeoCities page, the dance features rows of animated GIFs of hamsters and other rodents dancing in various ways to a sped-up sample from the song "Whistle Stop" by Roger Miller. In 2005, CNET named the Hampster Dance the number-one Web fad.

A multi-user dungeon (MUD), also known as a multi-user dimension or multi-user domain, is a multiplayer real-time virtual world, usually text-based or storyboarded. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, and non-player characters, and perform actions in the virtual world that are typically also described. Players typically interact with each other and the world by typing commands that resemble a natural language, as well as using a character typically called an avatar.

Eternal September or the September that never ended was a cultural phenomenon during a period beginning around late 1993 and early 1994, when Internet service providers began offering Usenet access to many new users. Prior to this, the only sudden changes in the volume of new users of Usenet occurred each September, when cohorts of university students would gain access to it for the first time. The periodic flood of new users overwhelmed the existing culture for online forums and the ability to enforce existing norms. AOL began their Usenet gateway service in March 1994, leading to a constant stream of new users. Hence, from the early Usenet hobbyist point of view, the influx of new users that began in September 1993 appeared to be endless.
