A holiday celebrated on February 14th, instead of Saint Valentine's Day, to commemorate the ending to A New Hope when Han Solo turned the Millennium Falcon around and attacked the Death Star, the Galactic Empire's ultimate weapon and battle station the size of a small moon. Without his aid, Luke Skywalker's X-Wing would've been shot down by Darth Vader and the Rebel Alliance would have been defeated. But Han Solo didn't do this for fame or fortune, he did it for Princess Leia, a girl who was banging her brother. He made himself into a fugitive wanted across the entire galaxy for a girl who showed no interest in him, and that is true love.
Guy: I thought of giving you chocolate and roses for Valentine's Day, but instead decided to get you this 8" Chewbacca figure for Han Solo's Day.
Girl: Oh I love you!
Guy: I know.
