A fictional term created by the heterosexual female community, out of annoyance for the time consuming nature of their boyfriends' bromances
A weak attempt at feminism
bf: "Hey wanna come over this evening?"
gf: "Nah, I got my girl over. We're in a sismance, get over it"
bf: "What the hell? That isn't even a real thing, and it sounds really awful when you say sismance out loud. You just wish you had a bromance like me"

the heterosexual relationship between females. It allows a lot more interaction than a bromance because they are females. "No homo" is implied.
Guy: "Hey! are you two in a relationship?"
Girl: "Nah. Are you dumb? It's a sismance. You wouldn't understand because you're a guy."

Guy: "Sismance isn't real."
Girl: "Well, neither is this relationship between you and me."
