Sunday Yodel

Also known as the Carpathian Shriek (see 1), is when an anus has been stretched to a cavernous width and thus has an acoustic or amplifying effect for sounds, primarily vocalizations. 1 The Carpathian Shriek is the same principle but with a vaginal cavity rather than an anal one.

I heard a Sunday Yodel of a Weezer song through the walls last night.
