What does fisting mean?
Fisting is a noun denoting a sexual practice in which one partner inserts an entire hand—and sometimes part of the forearm—into another person's vagina or rectum. Despite the vividness of the name, the word itself derives straightforwardly from 'fist,' the ordinary English word for a closed hand, with the suffix '-ing' forming a verbal noun; the practice is also known as 'handballing' in some communities. Fisting carries strong connotations: it is considered an advanced or high-intensity activity that demands substantial trust, clear communication, patience, and abundant lubrication to be safe. It appears most often in sex-education materials, medical literature concerned with injury prevention, and LGBTQ+ discourse, where it is discussed candidly. Outside these contexts the word is explicitly graphic and generally unsuitable for polite conversation, though knowledge of it is useful for anyone reading sexual-health resources.

- The sexual practice of inserting an entire hand into the vagina or rectum.
"The sex-education guide included a frank chapter on fisting and the importance of consent and lubrication."
"The manual stressed that fisting requires extensive communication, patience, and generous lubrication."
"Medical literature on fisting focuses primarily on safety practices and injury prevention."
Rarely pluralized; the word is nearly always used as an uncountable mass noun referring to the practice.
Though it sounds like a modern slang invention, 'fisting' simply borrows the ancient English word for the closed hand — and its clinical name, 'fist fornication,' appears in medical literature going back centuries.

Etymology of fisting
Fisting is formed from the Old English word 'fist' (the closed hand), attested since early medieval times, combined with the common Germanic '-ing' verbal-noun suffix. As the name of a specific sexual practice, the term emerged in modern English slang, gaining wider currency during the late twentieth century, particularly within gay male communities. A related clinical phrase, 'fist fornication,' appears in older European medical writing.
