Galimatias gal-i-'may-shi-us, n (French, gibberish)
Nonsense; a confused mixture of unrelated things. This very cordial-sounding word is extraordinarily useful in contexts where one wishes to inform someone that their ideas are bafflingly ridiculous and incoherent without seeming overly impolite. It combines the senses of 'incoherent' and 'ridiculous' into a unique and useful term.
The commentaries of the RBR faithful may tend to be Galimatias but the original stories by the authors are insightful, well thought out, concise, informative, and well appreciated.
