Learn how and when to remove this template message The modern usage and flexibility of fuck was established by the mid-to-late 19th century, and has been fairly stable since. The sexual connotation, usually connected to masturbation in the case of "go fuck yourself" or "go fuck yourself in the ass" , is invoked to incite additional disgust, or express anger or outrage. For example, "Fuck that! In this usage, there is no connection to the sexual meaning of the word implied, and is used purely for its "strength" as a vulgarity. Additionally, other uses are similarly vacuous; fuck or variations such as the fuck or fucking could be removed and leave a sentence of identical syntactical meaning. For example, rap music often uses the word fucking as an emphatic adjective "I'm the fucking man" for the word's rhythmic properties.
