NOUN-PHRAS
1. A string of exlamation marks (bangs), and other nearby QWERTY keystrokes (such as 1, @, 2, or ~) that appear at the end of JeffK-speak. Bang sequences used for an ironic or sarcastic purpose somtimes use spelled-out words to highten the hillarity (e.g., SCO SI TEH BESTEST LUNIX EVAR!!!!!!111111one~).
From Jargon 'bang' (exclamation mark) by analogy with 'escape sequence'.
