Happy Fuck You Year is the appropriate saying to send to someone who was shitty to you in the past, and you have no desire to wish a 'happy' new year. It is especially appropriate for ex's. Gets the message across quickly in a a mean, slightly stinging manner.
Karen to BFF: My ex was such a jerk last year... Lying, dating other people... I sent him this sexy selfie at 12:01 am New Years Eve and said "Happy Fuck You Year !"
