Bowel growl

To “go down on” or perform oral sex on someone’s anus.

If someone loves the tongue on anus action, you would refer to them as a mad bowel growler.

When one extends cunnilingus from port 1 to port 2, they are bringing the bowel growl into play.

I met this chick who's mad for the bowel growl

Hey, Frank, that chick at the bar looks like she'd love a good bowel growl

She's nuts for the bowel growl

With the economy the way it is, always remember, bowel growls are free
