a term that is hard to describe but is used in place of any word when playfully imitating someone else’s speech; also used as a noun as an affectionate nickname This word is used by me and a few friends, and I do not expect it to grow into a word that needs to be put in the dictionary. I wanted to include it because I think it is interesting how a meaningless noise can become an oft-used word in small circles of people.
