Okay, I was talking to my 81-year old father about my nephew/his grandson, and he said "his boyfriend" referring to my nephew's male friend. So I asked my dad if he knew something I didn't and he had no idea what I was talking about. It turns out he just meant his buddy.
Now, if he had said that about my niece and used the term "girlfriend" I would've thought nothing of it, but because he used the term, "boyfriend" about a strictly platonic buddy, it threw me.
When did the term "boyfriend" start to imply other than platonic friendship, whether it be between m/f or m/m?
Again, it doesn't apply to "girlfriend". I hear girls say "my girlfriend" all the time when referring to platonic friend, although, I believe as time goes on, the term is also gaining the implied meaning of something more.
