Bit late today, sorry about that.
I realized later that it's a little romantic and a little freaky, considering the lyrics. Oh well.
For those of you that have yet to know the story of Slepinir; Loki turned into a mare to curse a builder, and mated with the steed SvaĆ°ilfari, before giving birth to Sleipnir; "the best horse among gods and men". Now you know why there's so many jokes out there about Loki looking at horse porn.
