Slang. Words and gender.

Slang is the use of informal words and expressions that are not considered standard in the speaker's language or dialect but are considered acceptable in certain social settings. Slang expressions may act as euphemisms or as a means of identifying with one's peers. It is defined as a type of language consisting of words and phrases that are regarded as very informal, more common in speech than writing, and typically restricted to a particular context or group of people according to the Oxford Dictionary.
