For every girlfriend you get from that class you are obligated to claim 1 mancard from each male friend.
Can you elaborate? What exactly is a "mancard?" How do you obtain them, initially? Is there just a fixed number of them in the world, and you have to win them? Or do you get a pre-determined number of them at birth?
A mancard is a unit of manliness. When you hit puberty you automagically receive 3 mancards from nothingness. For every manly action you take when someone says you wouldn't, you take one of their mancards. If you say someone is going to do something unmanly and then they do, you get one of their mancards. When you run out of mancards you are obliged to do one of the following:
1. Get a sex change operation
2. Turn gay
3. Do something ridiculously manly, like juggle black bears, chainsaws, and loaded guns while eating fire
There is no maximum to the number of mancards you can have, and you can willingly sacrifice mancards for things, like seeing a chick-flick without a chick.
And don't be roped in, mancards are metaphysical! Don't be duped into
buying physical cards that say "Man Card" on them.
