There are many forms of this word, such as nucker (one who wets himself), nucking (wetting oneself, also used as a derogatory adjective), and skunk-nucker (someone who makes another wet himself, often by telling a particularly funny joke).
Actually, one could probably put the word 'nuck' into any context to add derogatory meaning. This meaning is largely used by people who do not know the true meaning of the word, but find its resemblance to the word 'fuck' amusing. The word was originally derived from the term 'nuke', meaning nuclear bomb, because the threat of such an object is enough to make some people 'nuck their pants.'
