There are Christian sects that are known to condemn dancing calling it a thing that is an act of the devil. Sinful is the term that they would use when these Christians are referring to what we simply call dancing.

When we speak of the people who dance and of how they are interpreted, many consider that the moves they make are an expression of the sin within them.
