Like a weasel - weasel like qualities in appearance and/or manner in humans. For a thorough examination of the concept see 'Dilbert and the Way of the Weasel'.
A certain economist comes across as a bit of a weasel, without naming names, I would say this economist is weasily, e.g. Ivan Krisskoff is weasily.
