A male character, usually in an animated children's movie or show, that fans gravitate towards to make NSFW art of. Onclers are white, skinny, usually dark haired men. The term comes from the phenomenon after the release of the CGI Lorax movie, where copious amounts of porn where drawn of the character, The Onceler.
Did you see all the porn that's getting drawn of that cartoon character??

Yeah, he's the fandom's new Onceler
