when a group of friends get together to help out another friend who has a problem, like drugs, manic depression, beating his wife, etc. usually involves an informal get-together during which the friends all sit down and talk with the person having problems.
im calling a cookout next saturday for jim, its gonna be his intervention: he's gotta stop doing meth and hurting his children.
i will never forget how my friends held an intervention for me and got me off crack. i owe my life to them
