I call my hubby 'Hunny' as he reminds me of pooh bear, you know round around the middle and talks alot lol.
I call my son Mr Magoo.....not sure why, just do. My dogs names is Zeus, but I call him knuckle head....because he has got a big solid head, a term of love really!!
I call one of my cats (Smudge) fat cat, becasue she is, and hte other cat (Harley) I call Little Boys....dotn ask me why the plural, I have no idea! He is only a small slight cat.
When I want to get my mums attection I yell out MA!!! She hates it, so responds lol. Most kids I meet that know me call me Fruitbat...as that was my scout leader name and it has kind of stuck.
