I guess a lot of kids do the same in our age! So here are some which I coined:
Guaa – Got generated from Ghumu (Coined by my Mummy) meaning walking around.
Kaawa – Its the short form of “Kawali” meaning I want
Ippi – Well its pretty close, but still my own copyright.. from word “Ippu” meaning open
Some more to come in near future.. Keep watching this space for updates
