I’m Down
In casual English, “I’m down” can mean “I’m willing,” “I’m interested,” or “count me in,” especially in response to a suggested plan. Because “down” has other meanings, including feeling unhappy, the plan or activity in the surrounding conversation is what makes the willingness sense clear.
In a casual plan, “I’m down” means “I’m willing / I’m in.” Use clearer wording in formal communication when the slang could be ambiguous.
