Variant of Commie.
1.) A
slang/derogatory name for a member or advocate of the Communist
party or movement.
2.) A name, used by some incorrectly but purposely, to
label and attack any person who is supporting politically leftist or liberal causes. Often creating a strawman situation.
Joseph McCarthy wanted to confront and eliminate the perceived 'Commi' threat of the 1950's with radical action.
An aggressive conservative might
label liberal candidates favoring some
socialist causes, such as universal health care, as 'commis' with the intention to
paint them negatively.
