The term "anchovy" is an adjective used to describe a person who promises to do something, but results in them going against their word. (Ex: Hypocrite)
Person 1: Hey, will you help me move out of my house tomorrow?
Person 2: Yea man, anything for a friend. I promise!
(The next day)
Person 1: Hey are you on your way?
Person 2: What? I never said i was coming over.
Person 1: Wow okay Anchovy.
