dookie is fine. It's your feable attempts at insulting others with curses that is unecessary.
try this:
Turbo, you big poopie meanie face. I hope your dog pee's on your house slippers at night and you put your foot in it in the morning.
OR another one thats a little more harsh but not as ass hole-ish:
Turbo, I hope someday you're in a situation with one foot in the grave and the other on a banana peel.
\You see?
Yeah, like this. Except, you might want to make then funny or, at the very least, witty.
