12 Guage and Rage 

When your suicidal but wanting some excitement.
You load the 12 guage shotgun and load a single shell, ready to go out with a bang but in style.

Person 1: "Dude I don't want to live anymore but at the same time I don't want to leave without a bang."
Other person: "Dude, play the 12 Guage and Rage!"
