Unsurprisingly, a character meant to represent the pinnacle of mysterious masculinity being babygirlified or bimbofied by Gen Z has the Call of Duty dudes pressed.
2022, Rachel Choi, "The babygirlification of Ghost in COD is threatening the incels", The Berkeley Beacon (Emerson College), 1 December 2022, page 4:
Ghost is, in its simplest terms, being babygirlified to the highest degree. Many predominantly female communities seem to be drawn to Ghost’s faceless and masked concept, low-toned voice, and general physique, deeming him their “babygirl” to express their fondness for him.
There’s an infantilizing undertone when fandom babygirlifies a fictional man, and some people also use the word in a horny way, echoing the meme of referring to characters as “submissive and breedable.” (See also: “He’s so babygirl.”)
