The counter to Scootabuse, a fan term which is Dash beating up or being generally mean to Scootaloo. Scootalove is the opposite, Dash being kind or, much like the recent episode, almost affectionate towards the pegasus.
Yeah, like a sister. x3 Seeing as Scoots was the only one without any kind of sisterly figure to look up to, and with Dash being the most fitting as her idol, the fandom put two and two together, and boom. Scootalove.
