Walnut Whipping

Another name for rosebudding; an act in which a performer voluntarily prolapses their anus for another perform to French Kiss.

My girlfriend pushed her rectum out of her sphincter and asked me if I wanted to kiss it and told me it was something called rosebudding. The prolapsed arse looked more like a red walnut whip to me, so I told her I wouldn't be walnut whipping her any time soon
