When one is "roughly" dating a girl but, for whatever reason, you do not want your friends and random slampieces to know that you are committed to that girl. Aka slightly less than dating but slightly more than just hooking up.
Donald: " Danny, I didn't know you were dating her?"
Danny: "Oh hell nah, we are just loosely affiliated"
Donald: "Oh congrats"
Danny: "Woooooooooo"
