The typical speed-dating event relies heavily on the “male approaches female” norm.
In most cultures, expectations about male and female dating behaviour (such as “guys approach girls”) are so entrenched that there are special days or dances where the script is flipped.
On Sadie Hawkins Day (traditionally observed in early November) or at a Sadie Hawkins Dance, women have the opportunity to invert social convention by asking men out on a date or to a dance.
If the male and female indicate mutual interest, the organiser gives them each other’s contact information.
If done efficiently, a speed dater could meet over a dozen potential dating partners in less than an hour.
