A [blarney stone]
A position where one person is lying on a bed with their head hanging off, and the other person is standing in front of them, like they’re about to do a plank and a blowjob at the same time.
My friend tried the Blarney Stone position and looked like he was about to fall off the bed and into the void.
My cousin’s girlfriend tried the position and looked like she was about to faint from the effort.
My brother tried the position and then fell off the bed and landed on the floor like a broken robot.
