A word used as a curse, often in place of 'shit', 'damn', and, most commonly, 'fuck'.
Often used or referred to by those who are
entertained by the play on logic of the 'Engrish'
phenomenon.
The word is derived from the Engrish
interpretation of 'black'; possibly started with 'black' mispelled on a condom package as seen on Engrish.com.
