Vadim84, shame on you...you don't read what I said.

warm-and-fuzzy = белый и пушистый = affectionate, amatory, fond, tender, devoted etc...

sorry, but ppl who lives and tougths by vocabulareis are very narrow...

"fuzzy words" = “нечеткие слова”,"путаные слова", "неясная речь", "детская речь" = gibberish, jabber, ribble-rabble, such words are deep context dependent, their meaning depends on the query they have been used. If You are not deep in context, father or mother of child, you can't understand them. They will have no sense for you.
Also it's such words is a half-terms in science, if you are non in context you don't understands when two mathematics speaks their language, but they speaks and understand each other speaking. It's not a slang! It's words that not born yet and possible they die tomorrow in that state! You can’t writes or reads it’s in vocabulary! In vocabulary is only “stable” words!
All diplomats always speaks fuzzy, using their fuzzy lingvo. American diplomats all known by their fuzzy words, example "we send a strong massage" it's can means - "now we will bomb your country, dude" or opposite "we must say something to you, please, hear us", it’s depends of political situation.

Shame on ...someone... that I must express this too you! Who are linguists in that forum?! You are or me?!

Lt. Columbo, you can't understands what’s means “Fuzzy Sapiens”, if not read the book. Because it's another fuzzy word that author used for describe thinking species. You can't get sense by googling it or just watch it in dictionary.
