Symbolically. For example, That umpire was completely unfair-let's burn him in effigy. Now used only figuratively, this term formerly signified a way of carrying out the sentence of a criminal who had escaped, such as burn in effigy or hang in effigy. A dummy was made of the criminal or a detested political figure and subjected to the prescribed punishment. [c. 1600]

Symbolically, especially in the form of an effigy: The deposed dictator was burned in effigy by the crowd.
