Parrot Expowhat

Like Parrot Exposition, but the expositor can't even finish the word. Even if it is easy to remember. Also used when someone says a big word, like Palaeo-whatsit. Sometimes used out of spite, and sometimes used out of disbelief. Often used in Advertising. Sister Trope to Gesundheit, where the speaker finds the word so unpronounceable he thinks it must have been a sneeze.
