I can't stand it when people type/write "back-peddle" instead of the correct "back-pedal," as in "You can't back-peddle now - you made that nasty statement loud and clear."
You normally pedal (e.g., a bike) to move forward; if you "back-pedal," you're pedaling in reverse, or moving backward. In the context of making a statement, you back-pedal to attempt to retract or reverse what you said previously.
If you "peddle," you're selling something. Not the same thing!
