Manic Pixie Fuckboy is a subcategory of Manic Pixie Dream Boy. While a Manic Pixie Dream Boy is a trope that derives from Y/N Wattpad fanfiction and Korean dramas, where the male love interest is a seemingly perfect, albeit pretty empty projection of protagonist's wants and fantasies (see Himbo), used to further the protagonist's story, a Manic Pixie Fuckboy is a more complex ans flawed character. A Manic Pixie Fuckboy on the other hand is elusive, almost Byronic in nature, but possesses an other-worldly and effervescent character that is hard to pinpoint. One of the characters that best embodies this is Felix from Saltburn, played by Jacob Elordi.
Felix is such a Manic Pixie Fuckboy, did you see how he has everybody wrapped around his finger?
