Definition of «crank»

"Crank" is internet slang for masturbating, usually used as a deliberately silly euphemism rather than a clinical or serious description of sex. The word often appears in playful phrases such as “crank it,” with exaggerated intensity making the joke more obvious. Its tone is bawdy, unserious, and knowingly juvenile, so it is especially common in meme-heavy comment sections. In this usage, forms such as “cranking,” “cranked,” and “crank” let commenters turn a sexual joke into an absurd running gag around a song or video.
