# Onii-chan Onii-chan is the Japanese honorific for older brother that anime fans outside Japan picked up in the mid-2000s and turned into an affectionate, meme-ready call for male anime characters. Between 2008 and 2014, YouTube clips, 4chan audio bits and copypasta spun the word into shorthand for the whole imouto (little sister) archetype, and it became one of the most instantly recognizable anime honorifics online. ## Origin The earliest Urban Dictionary entry for "onii-chan" was posted by user MishaMassacre on August 15, 2007, giving the plain translation "the Japanese word for older brother"[1]. The word itself is centuries old in Japanese, but that entry marks the point at which English-speaking anime fans started documenting it as slang worth defining online[3]. Early online use grew inside anime fandoms on 4chan's /a/ board and on YouTube. On October 18, 2008, YouTuber Joey Wu uploaded a clip from the Kyoto Animation series Clannad in which a younger sister repeatedly calls her brother onii-chan, giving fans a canonical audio reference to point at[2]. - **Platform:** Urban Dictionary (early definition) / YouTube (viral spread) - **Creator:** Unknown - **Date:** 2007 ## Overview Onii-chan (お兄ちゃん) is the diminutive Japanese term for older brother, most often used by younger sisters and by women addressing men who are slightly older, whether or not the two are actually related[1]. Online, non-Japanese anime fans adopted the word as a fond, half-joking way to refer to attractive male characters in anime and manga, and later to real streamers, VTubers and friends[3]. The joke works because of tone. The way little sister characters draw out the word in a high, sing-song voice became a genre unto itself, sampled in ASMR videos, reaction clips and shitposts. When someone types "onii-chan" online, they're usually invoking that voice, not the dictionary meaning[3]. The term also picks up an obvious NSFW second life. Urban Dictionary entries flag its use in hentai and incest-tinged jokes, and much of its 4chan/a/ and /sp/ mileage came from that edge[1]. ## How to Use People typically use onii-chan in three ways online. First, as a caption or comment on fanart and clips of an older male character, often paired with a wavy tilde or heart to mimic the anime voice. Second, as bait, dropped into a chat or thread to get an eye-roll out of anyone who thinks anime fans are too much. Third, as sampled audio, layered into edits, ASMR videos and shitposts that reuse the sing-song delivery from Clannad and similar shows[2]. ## Frequently Asked Questions ### What is Onii-chan?
