Galentine's Day is a fun, non-romantic holiday celebrated on February 13th (the day before Valentine's Day) for women to honour their female friendships, popularised by Leslie Knope from Parks and Recreation.
Unpopular best friends PJ and Josie start a high school self-defence club to meet girls and lose their virginity. They soon find themselves in over their heads when the most popular students start beating each other up in the name of self-defence.
