The word "ladykiller" is typically used to describe a man who is charming, attractive, and has a way with women. However, there are plenty of antonyms for this word that describe the opposite type of person. Some of these antonyms might include words like "repellent," "unattractive," "awkward," or "clumsy." Others might describe someone who is disinterested in women, such as "asexual," "hermit," or "celibate." Still, other antonyms might describe someone who is unappealing or problematic, such as "predator," "harasser," or "creep." Regardless of which antonym is used, it is clear that the opposite of a "ladykiller" is someone who is not particularly skilled or interested in dating women.
