When O'Reilly began to interrupt Dash, Cam'ron stated, "Why don’t you want to let him talk?  You mad.  You mad."  In 2004, the phrase was added to Urban Dictionary, citing Cam'ron as the coiner.

Bilingual dictionary: A bilingual dictionary or translation dictionary is a specialized dictionary used to translate words or phrases from one language to another.  Bilingual dictionaries can be "unidirectional", meaning that they list the meanings of words of one language in another, or can be "bidirectional", allowing translation to and from both languages.  Bidirectional bilingual dictionaries usually consist of two sections, each listing words and phrases of one language alphabetically along with their translation.  In addition to the translation, a bilingual dictionary usually indicates the part of speech, gender, verb type, declension model and other grammatical clues to help a non-native speaker use the word.  Other features sometimes present in bilingual dictionaries are lists of phrases, usage and style guides, verb tables, maps and grammar references.  In contrast to the bilingual dictionary, a monolingual dictionary defines words and phrases instead of translating them.

List of South African slang words: This list of "Afrikanerisms" comprises slang words and phrases influenced by Afrikaans and other African languages.  Typical users include people with Afrikaans as their first language but who speak English as a second language and people living in areas where the population speaks both English and Afrikaans.  Many of these terms also occur widely amongst ethnic/native South Africans, and others living in neighbouring countries such as Zimbabwe, Botswana, Zambia etc.  These terms do not occur in formal South African English.  Note when the letter "g" is either the first or last letter of the word or syllable, it is pronounced as an unvoiced velar fricative in the back of the throat.  Note, words ending in "-ng" are pronounced identical to those in English.  Note, in most cases of plurals ending in -nde, the "d" falls away in the informal pronunciation and spelling and the "n" is duplicated in sound and re-positioned within the degrees of comparison.  For example: Tande (plural of tand; "tooth"), formal = "tande", informal = "tanne".  In singular words' syllables ending in "-d", "-nd" and "-heid", the "d" is always pronounced as a "t".  For example: "ge-son(t)-hei(t)" (gesondheid, "health").  Note, the English term "slang" is used strictly in its English pronunciation in context, as the Afrikaans word of the same spelling (though pronounced as "slung") translates as "snake".
