A Shoot is something in professional wrestling that is completely real and is not scripted. In other words, broken kayfabe. A shoot rarely happens.
On the scripted level, a Worked shoot is a scripted segment that takes place in a show with elements of reality being exposed, such as an off-screen incident between wrestlers being used as fuel for an on-screen rivalry between them. It can also be a segment that fans are meant to believe is a shoot, but is not.
