When a man takes his flaccid penis and puts it a gagged earlobe, (male or female) and uses it as a makeshift cock ring. Then, when about to climax, place the tip into the middle of the clavicle. The spunk then drizzles down off the clavicle and on to the chest; leaving the nipples to look like a decoratively painted doorknob.
When I was with Skater Sam, we went back to my place and I gave em a Swedish doorknob. The design that came out was funky as fuck.
