Selfie Sticks
Everywhere Selfie stick has its own unique culture. I am sure there are plenty of areas, or at least circles of friends, where they are socially acceptable. Then there are some areas where they are not. Finally, I am sure there are a number of people who get made fun of behind their backs by their own friends.

I personally would not make fun of someone for using one. I think that's rude. Same thing goes for people who take lots of selfies or pictures of their food. They will sadly get made fun of a lot behind their back, because in Indian culture that's somehow acceptable but politely voicing your opinion directly is not.
