When one 'fingers' a girl whilst she's on her period, then when she's close to orgasm, slap her in the face, leaving The Mark of the Red Baron.
"I went at it with this bird last night"
"oh yeah?"
"Yeah she was on though"
"Ah dude"
"Nah it's alright, I gave her the slap of the red baron!"
"Yeahhhh!!!!!"
"oh yeah?"
"Yeah she was on though"
"Ah dude"
"Nah it's alright, I gave her the slap of the red baron!"
"Yeahhhh!!!!!"

When you are too drunk to realize a girl is fucking ugly and on her period and you continue to fuck her and realize the next day what you did.

This occurs during sexual intercourse while a woman is on her period. The man and woman begin to have sex in the standing up position with the man in the rear. After a while the man picks up the woman, and twirls her around the room during sex, causing some of her blood to spill over the place while she is airplane flying, thus giving the name "the red baron" to the woman.
Walking into Joe's apartment, you could see the Red Baron had visited at his girlfriends blood was all over the place

When you fuck a girl in her bloody pussy then slap your bloody dick on one ass cheek, slip it in her ass, then slap your shitty dick on her other cheek. Then cum in her ear.
Sarah was mad at me last night cuz I ruined another set of sheets when I gave her the Dirty Red Baron.
