Yeah, it's a thing.
It's kind of like Valentines day, but for the girls.
Here, I'll just let Leslie Knope explain.

And just like Leslie Knope, I think it should be a national holiday.
Not enough days to celebrate friendship if you ask me.
Although I have always been of the mind that V-day is a celebration of all loves, including that of the friendship-y kind.
But this year we are making it officially official!
So, happy galantines day all!
We will be commemorating with at-home spa treatments and tasty edibles.
