Verbally de trop? I think not.

I believe that people should use the english language...all of it. Expensive words must be used sparingly, but, if put to good purpose, paint word pictures that "um" and "like" cannot. (I'm still getting around to breaking that "like" habit.)

whiffle: to flourish a sword in sword dancing so as to produce a whistling sound

 spanghew: to throw violently into the air; especially, to throw a frog into the air from the end of a stick

poltophagy: thorough chewing of food until it becomes like porridge

lipogram: a writing composed of words not having a certain letter

gyascutus: an imaginary large four-legged beast with legs on one side longer than on the other for walking on hillsides

hapax legomenon: a word or form occurring only once in a document or collection of writings

mytacism: excessive or wrong use of the sound of the letter m (the “m” version of a lisp!)
