    Or you could say that a person waffles, or is a waffler.

  • Person who changes opinions too frequently and is overall inconsistent? You may try "politician" :P

1 Answer 1


You could say that person is flip-flopping (typically on some issue in particular).

To blow hot and cold is another, more general but seemingly less widely used idiom.

  • +1 for blow hot and cold, though.
