It doesn't matter how many people are in the picture It's still a selfie if you're taking the shot.
Maybe where I'm from? It's all over the internet too. Even google selfie. The damn Wikipedia page tells you the same thing. And the #selfie song should speak for itself.
I'm not a child. So maybe my "adultness" isn't up to par with that of a child's. However, if you look up the hashtag of #selfies, 9/10 times it's of a singular person.
I didn't say a selfie wasn't a single person. I was pointing out that fact that you are indeed wrong; a selfie is still a selfie if you take it with a group.
Selfie is when.you take the picture of yourself or with other people. If someone takes a picture of you, its not a selfie. If you take a picture of you (or pets, friends, family etc) it is a selfie.
