A fort made by a kid or a group of kids for them to hang out. A den is usually made out of large pieces of trash like old wooden planks and a tilet... Ok maybe not the toilet but I have seen one den like that!
An incredibly fick little nig who has a disgusting locker that he has to change every year. Den smells like fish and has beef with Dirty. Den enjoys fishing which explains the vile smell that he carries everywhere.
