I agree with Renholder and a little with everyone else.
With the whole "boys in the girls' room, girls in the men's room" bit, I immediately thought it had to do with transsexuality. Maybe about seeing a TG person in a public restroom and being unsure of their gender and whether they belong there or not. Public restrooms are a pretty awkward place, since you don't want to go in one and it's illegal to go in the other. I've been stopped more than once on my way in by people saying "Hey, that's the women's room!" and I have to just sigh and say, "I know." And I'm sure that most of the women in there must be thinking "...What's a boy doing in here? Is he lost? ...Is that a girl?"
I also think the song is making a statement about disregarding gender. Like "Who cares if it's a boy in the girls' room or a girl in the men's room? It doesn't matter. Be androgynous and look past all of that." I think it's talking about not making any decisions about a person because of their gender, because that isn't who they are. Maybe you're a straight guy or a straight girl (or at least you see yourself that way), but you never know when that one different guy or girl could come along and change everything for you.
In short, I think it's saying to just forget about gender. Gender isn't who a person is, so that shouldn't affect how you see them or stop you from loving them.
