A selfie is a kind of casual self-portrait. People often take selfies that include a significant other or multiple friends, and I’m curious whether there is any established terminology or slang for this kind of “group selfie.”
The linked Wikipedia article indicates that they are simply known as “group selfies,” but I suspect that there may be an older or better established term. I’m also curious whether there are specific terms for “couple selfies” featuring a significant other or best friend. Formal English, slang, and jargon terms are all acceptable.
