Skinny Love; noun - when two ponies love each other but are too shy to admit it while still showing it.
Fact #1: Rainbow Dash is gay and afraid to come out to her friends, especially a certain pink party pony for fear of rejection
Fact #2: Pinkie is pansexual, but is too afraid to come out to Rainbow Dash for fear of rejection
Fact #3: Somewhere along the line, Applejack got roped into all of this.
C'mon skinny love, just last the year.
(Or until Applejack loses her mind. Whichever comes first.)
