Another, more appauling version, of the Wet Willy. In this variation, one inserts their finger into their anus and then shoves it up the nose of an unsuspecting victim.

Though this can be done as nothing more than a cruel joke, it is typically executed when you want to humiliate someone and make them feel unworthy.
