I guess the word is basically an excepted grammatic abbreviation and has become a word in it's own right... as in non-descriptive ... hmmm, without any really identity of it's own... basically bellys don't really look much by themselves and tend to all look the same... just depending on the state of the mass that they are carrying... sorry.. my heads gone up my arse again and twisted around my intestines, simplicity and straightness to the pointness has waffed out of the window again!
