Offkey
Offkey describes someone who, out of nowhere, brings up the fact that they're on their menopause.
Example:
John the man: "Oh hi Sue. How was yr weekend?"
Sue responds with something Offkey like: "I spent it on my menopause. Happy now?" and then walks off in a neurotic mess, looking for her car keys, cos shes got Brainfog.
Something is Offbeat or uncommon .
