Guynamic - the girl to guy ratio at a social gathering orchestrated by girls from an all girls school, and the way in which this affects the overall ambiance.
"Dya think we've got a good mix of people coming to Bea's party?"
"We should probably invite Luke and Ollie, you know, to improve the guynamic"
Gayna is the type of girl you respect because she earned it. She is well-meaning, kind and welcoming, with a warm smile and a firm fist. She's a friend and confidant, she has your back no matter what- even if that means slapping your face and telling you you're wrong. Anyone should be so lucky to have a Gayna in their lives- if you find yourself among the lucky few, count your lucky stars and hope you don't piss her off.
