Why do we curse???

[Pieman]

understand the origins of each of the bad words and you will find an answer to why we cuss (not curse)
A curse is an incantation or wish of harm on another person ie. i hope you die
The colorful words we use were not always the negative things we know them to be

I disagree... not all curses are directed a people, or wish them harm. Cursing has become bigger than that... we do it when in pain, when we hate someone, when we joke around, and when we describe something. Curses have developed alternate meanings too. We find more and more uses for them as they become more natural.

My parents never minded me cursing, and occasionally a curse would slip out even at age 10 They only one they really minded was F**k... which I never let slip.
