No dotted eighths (3:1) in swing rhythm. For slow pieces ("ballads"), the relation is 2:1 (as in triplets), faster pieces tend to something like 3:2.

If you observe this and add some syncopation, you still ain't got that swing. Like other (imaginary) dance rhythms, such as waltz or rumba, there is a complex relation to muscle tension and brain waves.

For a rhythm to mean "a thing", it must be viewed in a larger context. Often a whole piece of music can be said to have "it" or not.
