Yeah, I think the question is only about ballroom dances generally, both competitive and social. Those who raise this question may want people to list dances they know as much as possible, I guess

Some more, I know that V.W. is one of 5 competitive ballroom dances (Int'l Style). I didn't list this dance because it is not often mentioned in professional program, both education / training and qualification (e.g. ISTD). But sure it is the best-known and most popular one danced socially
