A rare sexual position preformed chiefly by chemists (when they do rarely get some ass) in which the male will insert his tiny-man into an erlenmeyer flask and use the newfound implement to club his partner in a location of his desire. The broken glass remaining on his tiny-man can be left on as an act of revenge.
"Hey, did you see that scar on Mrs. B's face? Looks like she goten The Erlenmeyer!"
