"You keep using that word. I do not think it means what you think it means."
— Inigo Montoya, The Princess Bride (1987)
Two people using the same word while meaning completely different things has been a staple of comedy for centuries.
Lewis Carroll built an entire scene around it in 1871:
"When I use a word," Humpty Dumpty tells Alice, "it means just what I choose it to mean - neither more nor less."
