So I see you are a street boy. Slang is not proper English!
Slang is the use of informal words and expressions that are not considered standard in the speaker's dialect or language. Slang is often to be found in areas of the lexicon that refer to things considered taboo (see euphemism). It is often used to identify with one's peers and, although it may be common among young people, it is used by people of all ages and social groups.
