Kaley boi is always dead. He is a very beautiful creature, but unfortunately he is not human. This means that you may only admire his beauty, and acting on any sexual or romantic feelings is not allowed. He can be quite an exciting creature, but it is rare that you will ever witness him since he is dead extremely frequently. He is a kale and that is the best word that could be used to describe him.
"Wow, that is one hot creature!"
"Oh yes, that is because he is a kaley boi."
