a game typically played by high school or secondary school kids in the uk.
when someone says something which is deemed as saying something explicit or 'fruity' about the same gender results in them having to say safety to protect themselves, if they do not, someone who is also participating in the game has the opportunity to shout 'doorknob' which would result in the victim needing to touch a doorknob to save themselves from being beaten up. As soon as the doorknob is called, people participation have the opportunity to beat the victim up until he touches a doorknob or anything which opens doors. (not knockers).
