Sismance 

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."
