There is a reference to this name in the popular TV series "Friends" in the episode "The One with the Jam." Joey tells Monica "I just always pictured you ending up with one of those tall, smart blond guys, named like... Hoyt."
There is a Hoyt Street in Brooklyn, New York. I don't know the origin; if I had to hazard a guess, I would say it was the surname of someone noteworthy.
