Pants that fit so tight that when they are removed there are fecal stains on them because, due to there tightness, they came into contact with the anal orifice and were thus stained with feces.
Person 1: Would you like a pants pepper?
Person 2: Why what is that?
(Person 1 proceeds to chop the gonads, or "pepper" if you will).
Person 2: Ouch.. it burns.. silly me.
