The tight crease of skin where a man's nut sack meets the inner aspect of his right or left thigh. It is an area of the body that frequently itches and requires vigorous scratching, inside or outside of one's pants.
While waiting in line to see the opera, your wife whispers:

"Honey, for God's sake get your hand off your crotch. Here comes Mrs. Tatterhorn."

"I can't help it: my sclutch itches like there's no tomorrow."
