And if you have no idea what the 'offside rule' even is, does that definitely mean you're a female? Or simply an American?
I'm not sure that sports rules are a great test of gender. My wife can explain the NASCAR green-white-checker finish, and has several times, although it remains incomprehensible to me.
I guess it would be impossible to get each member lost? That way we could test their willingness to stop and ask for directions. I'm pretty sure that's a 100% reliable gender test.
