self-groupie

Or simply 'groupie'...
Much like a 'selfie', this is when two or more people pose for a photo that is simultaneously being taken by one of the photo subjects, normally with the intent to upload to social media after it has been taken.
Also like a 'selfie' this photo is taken with one member of the group extending an arm to capture all of the members (and his/herself) in the photo as well.

By the pure definition of the world 'self', Ellen Degeneres' photo taken with several of her fellow Hollywood stars at the #Oscars2014, could not have been a 'selfie'; instead, it would be referred to as a 'self-groupie' or simply a 'groupie'. This is not to be confused with the 'Groupies' that hang around stars and famous people, hoping to be seen or included in that lifestyle of glitz and fame.

Backstage Groupie

Tabitha spends a lot of time with musicians especially 'The Limp Dicks Band". She does their laundry, cooks soft foods since they're toothless loonies and performs sexual favors and engages in uncontrollable wild creampie orgy's. She's a backstage groupie slut who follows bands around while they're on tour for fanny fame. Backstage groupie/s like Tabitha flood their friends notifications on social medial with obscene pics of sexual acts some with multiple people. She also sucks dicks in between breaks and gigs. I blocked her because I caught my husband jerking off to the pics and he jet sprayed my computer. Backstage groupie/s should invest in tongue cleaners due to the amount of dry thrush like cum stains that are glued on their tongues. For all the teens out reading this, do not become a backstage groupie because there's more to life than Sex, Drugs and Rock & Roll.

Teen: I want to be like Tabitha a backstage groupie
Teacher: It's not a desirable lifestyle, just google 'backstage groupie' on UD and I guarantee you'll change your mind
