The Curse Word Challenge

[Dennis]

Dennis Meredith is writing a science thriller, the Tasty Bomb [www.TastyBomb.com] in which an eccentric main character, having been reprimanded for her foul mouth, has decided to employ non-curse words in her vocabulary as substitutes. The "Curse word" Challenge: come up with words whose sound makes them satisfying curses in times of anger or frustration. Examples:
Fricassee!
Pork chop!
Chopstick!

Flock, as in "Flocking birds!" Or "get the flock out of here!"
