Happy Valentine’s Day! Whether you’re out with your lovers are partying with your singles, here’s a few interesting tidbits about this day.

Turns out, it’s not just a Hallmark holiday. Who knew?

According to National Geographic News this holiday dates back to a pagan Roman festival called Lupercalia, during which naked men spanked young maidens with whips to increase their fertility.

I guess those Romans were into kinky.

This love fest happened each year on Feb. 15. But after a few hundred years of this fun, Christianity became the official Roman religion and they turned it into the legend of St. Valentine.

Whether this is true or not is unknown, but the story goes that Roman Emperor Claudius II told men not to marry — he was trying to keep his army strong. But Valentine went against this law and was executed on Feb. 14.

Sounds lovely. I think I like the Romans’ idea better. I’ll be out partying tonight — no whips, but hey, to each his own.
