look up any word, like donkey punch:
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"

"Yeah, and tell them to bring friends..."
