I know we have one but I can't find it. I'll have to look harder..
Bubby, the two (crappy) drawings below might help explain it.
It is corkscrewing counter-clockwise, and bending to the right.
The first one would be looking down on top of it, or look at the "back" of the bow.
Second one would be looking directly at the tip of the bow. The circle arrows show which way it is corkscrewing, the straight arrow shows which way it is bending.
It is straight as an arrow when un-strung, but as soon as there is any tension it starts to bend and twist.


Hope that makes sense.
Thanks
