For example I think the singer Norah Jones has a voice like chocolate, smooth and rich and velvety.  Nothing offensive there right?

So as a big nature lover I often use the medium of ‘animal’ to describe my loved ones. Misses E and M are my cheeky monkeys, or my little ladybirds. 

Ok so far?

But let me give you a word of advice.  Cough.

Referring to your boyfriend’s beautiful hazel eyes, gloriously shaded with long thick lashes as being “just like a donkey’s”, and his thick smooth manly skin as being like that of “a rhino” is apparently not generally well received.

Who’d have thought it?
