In gaming, the term "cuck" is typically used as a derogatory insult to describe a player who is perceived as weak or lacking in skill. It is often used to belittle or humiliate another player, and may be accompanied by other forms of harassment or toxicity.
However, it is important to note that using derogatory language and engaging in toxic behavior is not acceptable in any context, including gaming. Such behavior can have a negative impact on both the individual being targeted and the gaming community as a whole. It is always best to treat others with respect and kindness, whether in a game or in any other setting.
