vile - horrible
Somebody or something considered to be ‘vile’ is so despicable or loathsome that they generate disgust. It is a very strong word that suggests depravity, filth, and a sense of unacceptability. As it is quite a dramatic and forceful adjective, it can also be used for effect when discussing something like a taste or smell.
