funny story: I got the wife of a friend to install tinder, a couple of years back when I was dating. I was having a hard time getting matches, so I figured I'd see how the other side lives. She created an empty profile, with a blurry hippopotamus as a profile picture, and a single letter as name. Just "H". For hippopotamus. No bio. Within five minutes she was matching with every other guy she swiped right on. Which wasn't all of them, mind you. Within another five minutes, half of the guys she had matched with had messaged her. Regular looking guys. A lot of them had same opening line. "Did you know hippos are the most dangerous animal in the world?" After that, I got why I wasn't getting any replies >.<
