Stinky Bread - any bread other than sandwich bread. This started when we got zucchini bread after Nolan's birth, Calia proclaimed "I like this stinky bread" then when she had banana bread a few weeks later she stated "this is like that stinky bread" and hence the term was born.
Coupon - aka Cool Whip. I bought some of the new sprayable Cool Whip and told Kevin I picked it up "because I had a coupon" Later that night, when we had some on our brownies, Calia kept raving about the coupon, "I love coupon, more coupon, etc" It took us a bit, but we realized she meant Cool Whip...well the term stuck and now it's apple crish with coupon, pudding with coupon, and even stinky bread with coupon.
Noxious - aka Obnoxious..for example "daddy I'm sorry that I'm noxious"
I'm sure there are more, but these are just a few that come to mind and since this is Calia's onine baby book, I thought I'd share, since updating the real babybook almost never happens.
