If you're boring, just keep quiet and breed an air of
calmness/mystery around you. Answer questions and talk in a
relaxed, nonchalant tone.
Chicks dig these kind of guys like mad cos they seem cool and the
girls are intrigued to try to make them open up. They treat it like
a flirting obstacle.
One of my friend is like this. And he gets all the chiobus.

But if you break character, you'll be seen as a jerk playing hard
to get; so, good luck.
