The term "backseat girlfriend" typically refers to a relationship dynamic where one partner is not fully prioritized or is treated as secondary, often being kept at a distance while the other partner engages with someone else or focuses on other aspects of their life. This phrase can imply that the person in the "backseat" role is not actively involved in decision-making or significant events in their partner's life, akin to a passenger rather than a co-pilot.
Cid: "The killer used a different type of playing card to describe each of its victims.'
Alexia: "Ha Ha. You're still the same useless little pooch (Cid). Aren't you?"
Cid: "Miss Alexia, what's with the sudden backseat girlfriend behavior?"

The one that is always just there, they get invited but they are more of an extra in the background or… in the backseat. Mutually known but gets left out, doesn’t really know why they tag along.
There is a duo in this trio, why am I even here I am just the backseat friend.
I like hanging out with them, they keep each other entertained and I just get to stare at a tree or something, the backseat friend :)
