Top Definition
When you measure the length of your wank stroke and multiply this by the average strokes per masterbation session. This gives you the total distance you have to rub over you dick to achieve a hot steamy creamy ejaculation.

Note: Derived from wind-run which is the average distance meteorologists measure the length gusts of wind blow over.
While using the hot-shots radar gun and pretending to wank, the scatman recorded a velocity of 3 m/s. Therefore, multiplying this by an average wank time of 30 minutes, or 1800 seconds gives a wank-run of 5400 m. A pretty impressive wank-run compared to my premature ejaculation which gives my only a wank run of 20 metres.
