The Vietnamese word "nghị gật" refers to a type of person who is a "yes-man" or someone who blindly agrees with others, especially in a political context. This term has historical roots, as it was used to describe individuals who were selected by colonial authorities to fill positions in a fake parliament, often just to show support for the colonial regime without expressing any real opinions or concerns.
While "nghị gật" primarily relates to political contexts, it can also be used more broadly to describe anyone who is sycophantic or excessively agreeable in any situation.
