A female although brunette displays frequent bursts of typical blonde behaviour. Thus arises then comparison with the colour structure of a crunchie bar - brown outside and blonde within.
Jo - a brown haired girl - received a message from her mother telling her not to ring because she was under the dryer. On awakening to find this message, Jo promptly headed to the laundry where she observed that her mother was not under the clothes dryer, but at the hair dresser.

This is an example of a brunette displaying blonde behavioural characteristics.

Someone who's brunette, but "blonde" on the inside, ie. they have dark hair but are dumb.
Becca: *while swishing her dark hair around* "so.. like.. how do you spell orange?"

Tina: "oh my god, she is SUCH a crunchie."

mostly young, usually intelligent girls, who have brown hair, but will often surprise you with their remarks and behaviour, you will be left wondering why they are not blonde! brown on the outside but blonde (or yellow) on the the inside. just like a crunchie chocolate bar.
mikayla and haylee walk into the store and buy three chewing gum balls, 1 red and 2 orange.
they returned to the car where haylees sister says "i want the red one" so clearly haylee and mikayla are left with the orange. but haylee quickly yells "i bags the orange!"

mikayla thinks 'geez i love her, but haylees such a crunchie!'

A sound made instead of laughter. The sound is a crackling noise and is usually accompanied with a fist over the mouth. It is key to identifying a proper runaway laugh.
LeCharles was so amused when Quafonda spilt her red drink, that his crunchie could be heard all throughout Circuit City from the break room.
