It's a joke with your username.
lemme explain
In math, < is used to say something is greater or less than another value.
You made a little heart in your username, so it's basically Gabi loves Animal Crossing. But if you look at it a little differently, it looks like
Gabi < 3AnimalCrossing, so that would make your username say that you are... whoops i messed up the joke it would say that you're not better than 3 copies of animal crossing oh well it was funny anyways
