It grates on my nerves. I think the first time I heard it, I intellectualized it to be Dean refusing to bow before Castiel's Angel-of-the-Lordness, but now its downright annoying and it puts me off.

Like, why? he's not a little boy, he's a very powerful being whom should be respected and not dismissed with such a silly nickname. And it's not like Castiel is such a difficult name for an English tongue to pronounce.

Also? I may be a bit bitter about it... And Uriel's death.

I'm happy as a bunny with my lil' one!
