The lady, called Ingrid, stars in prankster David Mafra's video entitled "Fake Balls Prank". They are seen at the beginning explaining to the viewer that Ingrid will be wearing a fake "dong".

She is then seen asking strangers if they could rub sun lotion on her back.

The men first of all can't believe their luck, but then Ingrid asks if they'll do the front too.

She turns over to reveal the large "dong" and the men run a mile.

The first man is seemingly rather enjoying himself, saying: "Is it good right here?"

Ingrid says yes and asks if he can put it on the front too. He says "sure", and starts rubbing the lotion on her tummy before he notices her 'willy'.

He jumps and says: "What is this?". Ingrid laughs and replies: "It's my balls", and the man says: "Are you crazy? I thought you were a woman."

When Ingrid asks another man if he can put the sun lotion on her front, he says: "Of course, I can put on wherever you want."

But when she turns over he laughs and says, "What the hell is that?"

The woman replies: "What? My balls... don't you dig it?"

He says: "No. I'm out. Best of luck buddy. Bye Ingrid."
