the month and day when you first met a friend; celebrated annually, usually with drunken reminiscing
Omg, our frienniversary is coming up! Remember how we met? Damn, we were so drunk. Let's get a drink to celebrate.

Like an anniversary, this is the year mark for a friendship.
Be sure to celebrate your frienniversary with your friends who you remember when you met.
