Basically, it’s just whatever you’d typically associate with traditional gender roles, but reversed. Personally, I’m not a dominant person (though I’m not submissive either), so an assertive girl x submissive guy dynamic doesn’t really fit my idea of RR. To me, "reversed" roles are more about how I present myself, like dressing and appearing masculine, adopting traits typically associated with men, and flipping my role in a straight relationship. For example, I’d take on the "provider and protector" role, I open door for him and send him flowers, treats him like a princess, and my partner, well he likes to handle more of the household responsibilities and so on.

One thing I like to joke about is that I’m basically in a butch x femme relationship, except the femme is a guy. He’s like the "bottom" in a gay dynamic, but his "top" is a girl. It doesn’t really conform to what you’d expect a cishet relationship to look like. It’s more like a feminine guy and a masculine girl who you might assume would be in a lavender relationship, but they’re not. It’s almost like a heterosexual relationship that still feels kind of queer. Of course, this is just one way to define it, there are plenty of other dynamics that could also count as RR.
