Incredibly deep anal penetration, or buttsex, usually performed by a man with an incredibly large penis, whom is able to stimulate the receiver's jejunum in the small intestine.
Man: Hey baby, are you up for some jejunumal sex tonight? ;)
Woman: Oh hell yes, you know how much I love it when you are that deep inside my ass ;)
