haha me and my mates have a system where we go 'ding-ding' whenever we see a real swamp monster. There are few who understand the origins of 'ding-ding', but basically it's because we firmly believe that all ugly chicks, at some stage in their lives, have head-butted a tram. This in turn destroys their face, and the last sound they heard before they became a dogface was...ding...ding.
(If you don't have trams in your town, you wouldn't understand this concept)
