it's not pronounced "sucka" (like "sucker"), or even "sooka." it is a very specific "suuka"... like sugar, but with a /s/ and not a /sh/... "suuka."
whenever she is talking to or about someone, and she doesn't know their name, they are "suuka."
-- "c'mon, suuka!" - when she's beckoning a new friend to come play with her.
-- "suuka me a owie on auhm, mommy..." - when a little girl at MDO bit her on the arm over a toy.
-- "no, suuka!! dat mommy pate!" - when she was distressed over the waitress taking my plate at the end of our meal. (she really was so upset!)
it really is the cutest thing ever!
we have no idea what it means or where she got it, but it is oh so funny.
and we love it.
and we hope it is a very long time before she replaces "suuka" with actual names or pronouns! :-)
see ya lata, suukas!
