A panderer caters to what other people want in a crass way. This word is not a compliment. If someone in class calls you a panderer, maybe stop bringing the teacher apples every day.
A panderer is someone who tries to please others, not to help them but for an ulterior motive. A panderer kisses up to get something. A panderer is sometimes vulgar. Politicians are often panderers, especially the ones who say or do anything to get a vote or raise money. Pandering is dishonest because the panderer says what they think others want to hear, not what they really believe.
a person who serves or caters to the vulgar passions or plans of others (especially in order to make money)
