Bob did something that Alice... doesn't really like. Anyway, she decides to just laugh it off, and Bob begins to laugh with her. Then before he realizes it, she plants her fist deep in his face, sticks a knife between his ribs or pops a hole in him with a gun (her choice depends on her level of Ax-Crazy), with no trace of a smile on her face. They just had a moment of Pre-Violence Laughter.
Usually a case of Contagious Laughter, perhaps occurring before or during a Mexican Standoff, this is when two or more characters start laughing before one character draws a hidden gun or otherwise attacks the other character. In any case, one of two or more people goes from cheerily laughing, causing others to join in, to snapping out of it (quite possibly into anger) and doing something violent to indicate that they are getting dangerous. Going from laughter to serious violence always creates a Mood Whiplash. The event that caused someone to get mad could have just happened, or maybe way earlier, with the attacker wanting revenge. However, it does not have to be an attack on the other. A simple display of violence to give off a message could fit within this trope too.
This can be when something is Actually Pretty Funny, or may be a case of HA HA HANo. The character who makes the joke or laughs first is usually trying to distract the other. Essentially the opposite of Tension-Cutting Laughter. This trope can be combined with Turn the Other Fist. Compare and contrast Put the "Laughter" in "Slaughter". Also compare Conversation Casualty where a surprising act of violence is preceded by a calm conversation.
Compare and contrast with Dissonant Laughter, where the act of laughter and the not-so-funny thing are occurring simultaneously, while here the violence and laughter are happening after each other. It could overlap with Ominous Adversarial Amusement, when the apprehended opponent laughs before suddenly pulling an unexpected card out of their sleeve.
No Zero Context Examples please!! Add who is doing what kind of violence to whom, and what the context is they are in and/or why someone is suddenly doing something violent.
