I guess this is a two parter one, that involves a little context.
The Star Trek: DS9 crew are playing baseball against the Vulcans (Star Trek DS9, 7.04). Worf is a Klingon, and all they understand is violence.
The Vulcans are up to bat, and the crew members are calling out their various things ("hey batta batta hey batta batta"), and Worf yells,
"Death to the opposition!"Later, one of the Vulcans crosses the plate without touching it. Nog, who's holding the ball, asks what do to. Various things are yelled along the lines of "go tag him!", except for Worf, who yells,
"Find him and kill him!".
That made me laugh out loud.
