A common colloquialism for "jerking off" at the US Naval Academy. Perhaps the most popular pastime among male midshipmen, due to a natural aversion towards dark siding, a general lack of attractive young women, and the ever present fear of being SAPR'd. Not to be confused with the female equivalent, "plebing your cover", which is a play on the term for the way freshmen (plebes) carry their covers (hats) by spreading their hand on the inside and carrying by their side.
