A person who agrees with anything a person says to any extremity or range.
Usually referred to as a 'bitch', or a more kid-friendly way, "Yes-
man". Or if there are a surplus amount of
people that fall under this
definition then they are referred to as "Yes-men".
"I saw Andrew talking to someone and he was agreeing with everything he said, which is
weird because the
guy he was talking to was a neo-nazi talking about how Jews are evil? What a Yes-
man."
