(n) commemorating an epic and historical moment in time in which friends from different walks of life came together in celebration of their love of fitness, the outdoors, adventure and laughter, to form a bond, and a lifelong friendship unparalleled by any other group in the history of mankind.
This July 4th will be the first friendiversary of that stellar summer day we all met and became the best of friends.

Friendiversary (n) is a dumb non-word, but used on the Disney channel in current kids culture which easily gets stuck in your head.
Jeffrey, Happy 10 year Friendiversary! It was this week 10 years ago that we met - can you believe it?!? :)
