Proposal

In internet slang, the term “Proposal” is commonly used to refer to a hypothetical situation or idea suggested by someone. It is often used as a way to present an idea, concept, or question for discussion or consideration among online communities.

Examples:

In a gaming forum, a user might propose a new feature for a popular game, like “What if the game had a multiplayer mode where players could team up to complete missions?”
On a social media platform, someone could propose a question to spark a conversation among their friends, such as “What if time travel were possible? Where and when would you go?”
