When they were kids my mom and her sister created their own secret code language. Spoken rapidly, it’s tough to follow unless you have a lot of practice.
Theeezis eezis eezan eezexeezampeezle eezof theezee Eezaleezabeezameeza Eezeez.
My daughter is very into it and of course now speaks it way too fast for anyone to understand. I figure it’s gotta be good for her brain, even if it makes my head hurt.
