To wish to, or to fully engage in a sexual act of some sort, but the term 'Cun' now is typically used to imply consensually sharing naked images
back and forth from someone you're attracted to over Snapchat. An
evolution of
phone sex.
Derives from the word 'Cunilingus', one of the more taboo sex acts. Is usually used alongside the word 'finna' meaning 'fixing to' or 'wanting to' (i.e, "I'm finna cun that girl"). Easily mistaken for the word 'cunt'. 'Cunning' someone refers to engaging in a sexually act, or silliciting raunchy images from another.
