This game's main idea is quite similar to Boys vs. Girls. You choose boys' or girls' team and need to fight the members of the opposite sex. However, this is not a side-scroller, but rather a skill based shooter. You need to collect different items and launch them defining the power and the angle the way they will hit the enemies. In the boys' game the items are dirty socks and other disgusting objects, while girls' projectiles are exclusively feminine.
