is there something called the "American quarter of an hour" meaning that it's a specific part of the evening at a club when it is the ladies who invite the men to dance? I am translating from French where they call it quart d'heure americain, i.e. the American quarter of an hour, but not sure if that will be understood in English?
I believe this is called Ladies' choice, but I am having a hard time finding supporting references other than a remark on Wikipedia:
Ladies' choice is a dance term to indicate it is ladies' turn to choose partners.
A variation on the answer @michael.hor. In Britain this was more popularly known as:
A ladies excuse-me
(There should probably be an apostrophe after ‘ladies’ but I don’t think there ever was.)
As a source for this, I cite a section from a BBC page ‘WW2 People’s War' :
BUT now and again the MC (our vicar rubbing his bony hands with fiendish glee) would announce a “Ladies choice” or a “Ladies excuse-me” dance.
Obviously a little dated.
