Blued is a social and dating app widely used by gay, bisexual and queer men, particularly in China and across Asia, where its notification alerts are part of everyday phone use. As short clips and memes featuring phone screens spread on TikTok, Instagram and YouTube, the app's distinctive chime began appearing outside its original context as shorthand for a message, a match or an awkward notification. Creators keep using it because it is instantly recognisable, short enough to drop into a joke, and carries a social meaning that a generic phone ping does not.
