Shoe

An item that when used correctly, especially by angry, foreign reporters as a display of cultural and personal disdain apparently expresses a negative message which is more directly and coherently received than other messages such as protests, letters, losing elections, global disrepute, criminal proceeding, obviously failed policies including but not limited to the economy by a certain unpopular president who otherwise is apparently immune to consequences of ignorance, hubris, incompetence, being schismatic and misusing authority.
