Someone loses their cool at some offense another party committed to them and attempts to give the target of their wrath a No-Holds-Barred Beatdown, requiring a third and usually a fourth party to hold back the irate one shouting something along the lines of the trope title before violence breaks out. Frequently found in a Crime Time Soap or Detective Drama, where it's a detective (rarely a great one) angered by a possible or actual perp being smug and possibly threatening someone else, lunging for them and needing to be restrained by fellow officers. This is not usually part of a Good Cop/Bad Cop ploy, instead being sheer anger or hatred on the part of the detective (often when It's Personal). Particularly vulnerable to stuff like If You Kill Him, You Will Be Just Like Him! when there is actual murderous intent (this is quite rare in police shows, though).

This trope is very easily Played for Laughs both within and outside the police procedural. Nastier examples, however, may very well overlap with Trouble Entendre or Reminiscing About Your Victims. Compare and contrast with Held Back from the Carnage, where someone is stopped from rescuing someone or offering assistance in a bad situation (though they may overlap).
