Mumble Jumble 

Speaking without thought; talking like an un-educated person on a subject they know nothing about; giving an answer to a question that has no relevancy to the question; Sean's cousin Bob gave a Mumble Jumble answer (not Mumbo Jumbo Dr. Bob).

Bob gave a Mumble Jumble answer to Sean's simple question about a fishing trip.

mumble-jumble 

Intense mumbling that some people do in a conference-call when they start discussing something at one end, oblivious of the fact that it can't be heard - or understood - by participants at the other end.

My tricky question stumped the unprepared team in the US and they went into a mumble-jumble that made absolutely no sense to us at this end.

Mumble Jumble Woo 

The annoying and infuriating word posts that abuse other races or religions.

The posters of these words alienate a number of persons of the insulted race or religion, and therefore triggering a mass number of opposing new posts.

This process continues perpetually, at each time consuming more people until nearly thousands of users are posting, enraged by as little as one miniscule post.

The process is exhausting, yet practically stupid. Most users involved in this war of words, are unaware that it was probably started by a fool with nothing better to do than to degrade other races or religion.

1. Americans Watch too much FOX.

2. The British Drink too much tea.

3. Australians have too much native wildlife.

(Note: I do not support any racial conflict, these are just examples)
