A metaphorical engine that starts when good drama is heard.
Also can be started by a provoking statement. When the engine is started the person will spew random bullshit from their mouth (ex. talking) and start a conversation. Each response from the drama engine will be a drama laced comment; providing no resolution to the conflict but to only exasperate the situation.
(a drama evoking message is sent through facebook chat)
"Dude, don't answer that. that's defiantly going to start her drama engine."
