"Offensive odor" or foul smell is a common problem that concerns most of us. However, there are many different expressions that we can use to describe such an unpleasant scent. Some synonyms for "offensive odor" include a malodorous or noxious scent, a rank or putrid smell, or a pungent or acrid aroma. Alternatively, we may talk about a stench or a reek, or highlight an odor as foul, repugnant, or disgusting. Whatever term we choose, we all seek to eliminate offensive odors whether they come from our bathrooms, kitchens, or bodies, so we can enjoy fresh, clean air throughout our day.
