GO 15-18— ORIGIN, MEANING & USAGE

go 15-18 « Go 15-18 » (« va sur le 15-18 ») is what one tells a poster on the Jeuxvideo.com 18-25 forum to say they belong on the 15-18 forum, that is, that they write like a teenager.

Origin:The 15-18 forum (« Blabla 15-18 ans ») of Jeuxvideo.com was created on 17 March 2004 when the general-chat forum was split by age, according to the JVFlux wiki; after the site's 2014 redesign the 18-25 forum became the busiest. Telling someone « go 15-18 » sends them back to the younger forum and so works as a put-down aimed at immature posters; users of the 15-18 forum themselves tend to see it as an insult. Forum threads show the phrase in use by 2016, one of them lamenting that it had become an insulting expression, and a 2018 thread parodies it with a mock tutorial (« Comment « Go 15-18 » ? »). A poster in the 2016 thread says an older version of the phrase was « go -15 ». The first use is not documented. The forum itself is covered by « 15-18 »; this term is the phrase used as a retort.
