jelqing
n.— «The old-school cornerstone of P.E. is an exercise known as jelqing: gripping the base of the partially erect penis with the thumb and forefinger in a tight OK sign, and pulling upward to the head. Milking yourself, in a sense.…A typical beginning P.E. routine, as dictated by Mike Salvini, might include 300 jelqs a day.» —“Size Matters” by Peter Rubin Salon Apr. 12, 2005.
