Boo is accident (like bopping someone off the head, knocking them down - innocent face) 8)
Letters: A = pah B = bah C =kah D = dah E = Gee
Might be easier if you add mine to your list. There's a few more things I've been working on to figure out what they mean or want.
"Umm do?" (no idea what this means, but usually said when just sitting still or kneeling, in chatty talk)
modifying post because there is no 'reply' button.
A few more comments I've tested out;
Na-na = banana, most often said as Bah-nah, sometimes it's said a bit different than the doll which seems to be more pronounced on the end (nah-NA for doll) (NAH-nah for food)
Boo-Koo = book, guess they want storytime ;D I hear this one a lot, lol
Umm, Do - also Ah-Do? = seems to be when not much going on, as in scanning thru the clothes etc.. I'm wondering if they want to 'do' something but not really caring what. I'm thinking it's possible they're asking what we are doing?
Bee - I've been hearing this a lot, but at first thought I was not understanding. The other day Clancy was in a chatty mood & used it quite a bit. I turned up the sound & listened closely to be sure that was what he said. I have no idea what it means.
Ah-Kee - I hear this one just about every day & not sure of it's meaning. The only thing I can think of is keyboard, but most often they will use one of the other references if you don't respond to one.
No - Other than refusing something, I hear this occasionally for no reason. Usually during chatty time. It's most often repeated during chats.
