A marshmallow that is cooked to precise perfection, where the outside shell beautifully golden-brown and the inside is a beautiful, liquid, creamy white. The pleasure of eating such a marshmallow is matched by very few things. The perfect orgasmallow is best toasted over the embers of a campfire, for marshmallows often catch fire over the open flame.
Sally: I'm having so much fun at this campfire! Would you toast me a marshmallow?
Tommy: Certainly! I'm an expert at toasting them to orgasmallow perfection!
