Can I nominate "Gourd" to the dictionary? It is pronounced just the way it looks, and is the generic name for either of the two standard basketball positions which are not forwards or center. It was coined by Dick Vitale and used ad nauseum by him ever since. Not sure this really qualifies for admission, as it is not slang per se, but rather just dispronounciation.
How about "untracked", which they all use when they mean "on track" or "unstuck"?
