Adjective

Definition: expressing a low opinion of someone or something; showing lack of respect for someone or something.

I recall  Prof. Rosen using this word as she was explaining the word “cooze”  in Tim O’Brien’s The Things They Carried.

“Cooze” is in fact a derogatory word for describing a woman because it is showing lack or respect and expressing a low opinion of someone, in this case a woman.
