Oh dear :S I am a master of embarrassing names, both for my unfortunate pets and my husband.
But yes, basically, I call him "person" and "guy" endearingly, and any combination of them (such as Person McGuy, I know, I'm a total weirdo), he calls me "person" as well, and it all started with South Park and the Canadian Argument (

Haha, yeah, funny how these things evolve
But "person" is definitely our equivalent of "honey" or some such thing
and we sometimes just randomly say it to one another to let the other know we care
