Didja ever notice this? A few guys and chicks will go out together, or maybe it's just them having a drink after work. One of the chicks will get up and invite one or more of the other chicks to go to the bathroom with them! Huh? What's that about? Imagine guys doing that: "Yo - Jake, Slim, Lefty - ya wanna go to the bathroom?"
Why do they do that??
