Ball pillow
The pillow used to strategically keep a man’s regular-sized to gigantic balls from being squished during PM sleep, nap-time or siestas.

This pillow is typically folded in half and put between the knees in the fetus or “spooning position”.
Boy: Baby, can I use that extra pillow as my BALL PILLOW tonight?

Girl: Nah, you know that pillow is for decoration only and I don’t want you stinking it up with your nasty ball sack.

Boy: Okay, then can I just use your face as my BALL PILLOW?

Girl; Sure.
