A layer of semen on a girl's face in areas where facial hair is commonly found on men, e.g. chin, upper lip, cheeks, neck. Usually results after a blowjob.
"Do you want a blowjob, sweetheart?"

"Yeah! How do you want it to end today, honey?"

"I'd love to have a Merlin's Beard, but whatever you want. It's your special day."

"You want it, you got it!"
