n. an act similar to the "Wet Willy" involving the insertion of one's finger in one's own rectum, and then placing it into the ear of another. Other variations of this are the "Stinky Wet Hank", used with diarrhea; and, the other, with the substitution of one's finger with one's own penis.
Emo Pat (coming in crying tears of joy): Oh, fellow confidants, my dear yonder Rachel hath given me ye olde stinky hank last night in mine horseless-carriage upon the misty mountain hop!
Confidants: FAR OUT!
Rachel (smashing through the wall): And, he returned the favour...BOO YAH, GRANDMA!
