The old "duck 'n' mumble is an age old technique for avoiding any one who seeks to interupt you in your never ending quest to buy shite from shops. For instance, Big Issue sellers, strange middle #age women with clip boards who "only need a minute love", or the vultures from the compensation companies.
Basically, you bow the head slightly, perhaps with a look away from the idiot in question, and mumble an apology.
{Big Issue Joey}: Biiiiiiiiiiig Isssssue saaar?
{You, giveing the old duck 'n' mumble, and talking in a barely legible way}:*mumble* no thanks mate* *mumble

This can be replaced with "I'm too busy", "Sorry mate", or a personal favourite, "Piss off"

A word 80 year olds or edgy 13 year olds use to describe modern hip hop song where lyrics aren’t super deep and meaningful. Not all songs are going to have deep lyrics and not every song from the 90s was Brendas Got A Baby. You guys need to open your eyes sometimes.
13 year old: Ew I don’t listen to that mumble rap shit

The language generally spoken by non-native English speakers in the tri-state area(North Jersey, New York City Suburbs and Southern Connecticut). Usually it is spoken fluently by cabbies, gas station attendants and mini mart clerks.
I could not understand Abu at the 7-Eleven when he tried to give me a free bag of Doritos because he was speaking the tri-state mumble.

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)

The gross crusty white shit that forms in the corners of old people's mouths when they talk.

A genre that does not exist with racial undertones. While yes it may be hard to understand some words it does not make the music bad. Any one who says it is not “real music” are usually white and listen to country.
