gayniversary 

The anniversary of a gay person's coming out.

"Tuesday's my gayniversary - four years since I drunkenly admitted I was gay in a game of circle of death."

Gaynniversary 

noun.- derivative from the union of the words gay plus anniversary, resulting in a comfortable way to express a year out of the closet.

Today is Mike's, gaynniversary, who would've thought he was in that big closet.

Granniversary 

The anniversary of becoming a Grandmother. It should be a special event every year for being bestowed with the honour of guiding a new life through the world's everyday challenges.

Tomorrow is my first granniversary and I plan to celebrate it by taking the day off with my granddaughter.
