First World Problems are frustrations and complaints that are experienced only from wealthy people in rich countries. This hashtag is typically used as a way to make a joke out of unimportant inconveniences. At first, this hashtag seemed kind of funny, I've seen complaints that I personally have also experienced. But if you look further into it some people may be very offended by it. The first world is a term associated with already developed countries whereas the third world is associated with countries that suffer from poverty and are underdeveloped. To me this hashtag is a harmless joke but some would argue that is shouldn't be used on the internet as it is not correct because the third world doesn't really exist any more.
