Originally a search engine abbreviation to query the website Urban Dictionary, “urdict”, a play on the word, edict, denotes any term that has gained sufficient everyday social currency to merit inclusion in the official English language canon, despite it’s technically unofficial linguistic status. In other words, its degree of usage is such that — as an edict of sorts — it’s colloquial legitimacy and cultural significance cannot be refuted.
Everyone is using 'lol' now, and I know it's not in the dictionary, but we all know what it means and use it in conversation everyday: it's an unquestionable urdict.
Urdish, a blending of the words "Urdu" and "English", is a hybrid of English and the south Asian languages and basically means to combine both types of words in one sentence. This is more commonly seen in the urban and semi-urban places of the Urdu speaking areas of Pakistan. It is also used by many British Asian families to enliven standard English.
