The Estonian jackhammer

When a man spreads the woman's vagina flaps and attempts to stick his head into it. This normally ends up with a trip to the ER as it is not safe for both genders. This can be done with the same sex (see Finnish jackhammer).

Brian: "so I gave Sandra the Estonian jackhammer last night!"
Andre: "is she ok?!?"
