bending my whistle 

To annoy, aggravate, or upset. Similar to jerk my chain, grind my gears, or twist my nipple. Refers both to the fact that a damaged whistle will not sound and also to bending the pitch of a whistle's note, i.e. changing one's mood (in this case, for the worse). Some read slight sexual innuendo in it.

"Did Leroy send you another stupid chain email?"
"Man, that guy is really bending my whistle."
