Khalas

Khalas is an internet slang term often used to express a sense of finality or conclusion. It is commonly used in Middle Eastern countries, particularly in Arabic-speaking communities.

Examples:

After a long discussion on a forum, someone might simply say “khalas” to indicate that the conversation is over or that they have made their final point.
If someone is tired of arguing about a certain topic with their friends on a chat group, they could say “Let’s just put an end to this and agree to disagree. Khalas.”
