Taking into consideration that she's a millennial who was on the internet when unicorn themed stuff and memes were a thing (and some past life stuff), I don't think it's an intentional jab, she probably thought it's going to be cute and fun to put it there.
But even if it is a jab, it's so fucking funny seeing /here/ meltdown over a short clip, while people on this board have been continuously shitting on her for the past year, calling her names, fantasizing about her having sex with homos, or accusing her of destroying the walled garden. It's so pathetic, my god, you people are so fucking pathetic
