I have grown up with several nicknames - my father called me tuki-tuki and for the longest time he called me papa which means kiddo in telugu.
My cousins and friends call me anything from ambi to binx to biki to bika to binca, whatever they fancy.
I call the other A 'Da' and he calls me 'Di'. Sometimes i call him 'Jaanu' in public which he finds embarrassing (i am trying my hardest to stop calling him that, in public at least!).
Do you have a nickname or more than one? Do you find it silly / embarrassing?
PS: That's my dad and i.
