Some guys want to have girls that are "like the boys" as in they don't act "girly" and they act more "guy-like". An example of this statement is that that girl would rather play video games with the boys instead of go to the mall and buy stuff that'll probably put them in significant debt, but wouldn't really acre about this obscene debt and will keep shopping; another example would be the girl having a similar energy to guys instead of her stereotypical "girly" energy; etc.
So to sum it up in a way, boys want girls to have a similar energy as the boys.
