When you are facing cataclysmic/apocalyptic events and you would like to have sex at least one more time before your life is over

To kill yourself

A phrase often told to someone caused by aggravation. A common antonym is "Go bang yourself". It basically means, "stop wasting my time and stop being mean."

Overused lyrics used in many MSN display names and signatures on form sites.

'Bang Bang Guns Go Bang' is from the song 'Kiss Me, I'm Contagious' by From First To Last.

'Bang bang guns go bang' is chanted in the chorus of 'Kiss Me, I'm Contagious', a well-known From First To Last song.
Possibly the WORST fad ever.
Used by "scene/emo" kids in their MSN display name, signatures (mainly Neopets) and on their Myspace profile, sometimes as a picture caption.

Usually accompanied by hearts (<3, </3, ect.), a badly cropped pistol or a picture of someone holding their fingers to their head, like a gun.

A more polite British way to tell someone to go away. See also fuck off for the more offensive term of the same meaning.
