Friendversary 

Much like Anniversary, only with how long you've known a friend.

Person A: "Come next month, I'll have known Person C for a year."
Person B: "Happy Friendversary!"
Person A: "Thanks!"

freniversary

1. The celebration (on a chosen day) of your length of friendship with a particular friend. Like an anniversary but without the promise of sex afterwards.

2. Acknowledging the tenure of friendship you've had with someone by arranging a special "hang-out" day.

3. A platonic date to honor your friendship.

"Hazel and I are celebrating our freniversary by going out to dinner at CPK then watching a movie."

"Dude did you know we've been friends now for over 6 years?"

"No way! We should have a freniversary to celebrate how awesome we are!"
