We had the same situation happen when I was in college way back in the 80s.
African American kid. Living illegally in the campus-approved dorms. Harassing all the girls. Dressed in school clothes. Going to all the parties. School authorities who would do nothing for months on end.
He was an Ivy League fantasist living the dream.
There was an old TV show back in the late 60’s early 70’s that had as it’s premise a kid who was attending classes at some college trying to get an education but had no money. He would attend classes under an assumed name of someone who was out sick or absent.
And the dean was always trying to catch him.
I can’t remember the name of the show...............
