Kutenay,
I LOVE granola! If it weren't for the stratospheric caloric levels - I'd eat the orange Harvest Crunch three times a day.
To me a "granola" - when applied to a guy - means he's a starry eyed idealist, who knows nothing about how nature really functions, he's left wing - in all aspects, he wears hemp clothes and probably has a pony tail - whether he's grey, balding or not. If it's a "she-granola" - much is the same except she wears long wool skirts, never shaves he legs or armpits and only wears tie-dyed tops and bandanas.
Eating granola, my good man - does not make you - "a granola."
You see, Kutenay - teaching teenage kids (and having three under that age living with me) - keeps me up to date on the latest vernacular. Perhaps you don't have that advantage.
I'll try and remember that when writing.
