Splitting the Red Sea 

Having sex with a girl on her period.

I raise my rod in Egypt and I split the Red Sea,
That means I had sex with a girl on her period, that's right,
I don't mind ketchup on my hot dog as long as the bun is tight.
-Jon Lajoie, Very Super Famous
Splitting the Red Sea is a controversial act, some don't mind, but I prefer NOT to have ketchup on my hot dog.

When you engage in sexual intercourse with a girl during her period and you get a bit of blood on your genitalia.

Dude, I just was splitting the Red Sea with Tammy and her blood won't come off.
