Coucou is a name used by “harries” and “Larries” to use on Harry Styles’ crazy ‘ex-girlfriend’ Camille Rowe. The name started when Harry Styles wrote a song on his album Fine Line called Cherry and Camille is talking French at the end of the song (which is scary) and she says coucou. So then fans started calling her couco.
Person 1: Did you see what coucou posted on her Instagram??

Person 2: Yeah… it was a bit crazy
