reverse Frosty

In the 1969 film, Frosty the Snowman, the titular character is seen springing to life after children place a magic hat on his head, exclaiming “Happy Birthday!”. The reverse Frosty is where you wish someone a happy birthday and then completely ghost them for the rest of their life.

Me: “why hasn’t he reached out to me?”
Friend: “His birthday is coming up, time to reverse Frosty his ass”
