sentences:  An interjection of "whatever" can be considered offensive and impolite or it can be considered affirming.In the late 20th century and early 21st century, the word became a sentence in its own right; in effect an interjection, often but not always, used as a passive-aggressive conversational blocking tool, leaving the responder without a convincing retort.Early examples of current usage include a 1965 episode of "Bewitched" in which the character Endora exclaims "Alright, whatever" to her daughter, lead character Samantha Stephens, and also the much maligned 1965 sitcom "My Mother the Car", in which "whatever" was the standard retort used by Captain Manzini (Avery Schreiber) whenever he would mispronounce "Crabtree" (Jerry Van Dyke), the car's owner (son).
