Definition & Meaning of "beta cuck"in English

What is the origin of the term "beta cuck" and how is it used?

"Beta cuck" is a slang insult that appeared in online communities in the 2010s, combining "beta" (a submissive, low-status man) with "cuck" (short for cuckold, a man whose partner is sexually unfaithful, often used to imply humiliation). The term emphasizes both weakness and social or sexual emasculation, portraying the target as powerless and contemptible. It is mostly used in internet forums, memes, and political or manosphere rhetoric to mock men perceived as lacking dominance or assertiveness. The term is highly derogatory and intended to insult or provoke; it is never neutral.
