Trust me, it's entertaining. If you like watching concerts, tutorials on how to do something, people scoping random things, hot men, drama between people who broadcast, nudity (Periscope doesn't allow this but people do it anyway), or trolls in the comment section, this is the app for you. It can be messy, but it depends on who you follow.
I don't have this but everyone seems to be using it or want to use it these days? 
Spill the tea.
