When Arwen was new, she quickly decided that the Crazy was the coolest thing since sliced bread and began a campaign of trying to lure her into cuddling and playing together, plus copying everything she did, which included stealing her seat whenever she got up. This, coupled with her enthusiasm, led to us calling her the BBHBIC (the Crazy is obviously the true HBIC) after Allison of American Idol (American Idol trivia is one of our household's primary fandoms. Haven't you heard how healthy and statistically inevitable it is for people to adopt to some extent their spouses' hobbies?). This quickly evolved to bbkitty, and now we call her "BB" a good 75% of the time corresponding to when we call Tea [the] "Crazy" instead of Tea.
This led to my pondering the fact that Perry only has one name. I mean, I also call him baby, sweetheart, darling, dumbass, and puppy, and Wax calls him dumbass and dog, but this just corresponds to calling either cat kitty, which also happens. He has no proper nickname. Maybe it's because his name already has two syllables and ends in -y?
