HappyJack,
You have understood bogbeagle correctly. This is type specific, but in broad terms what will happen is this.
The elevators produce a downwards force, which causes a pitch-up moment. (This is cancelled out in steady flight by other forces, such as drag and lift.)
With the aircraft close to the stall, stall warner going and possibly even some light buffet, apply power whilst holding the control column still. The increased airflow over the elevator will cause an increase in the amount of (downwards) lift produced by the elevator. This in turn causes the aircraft to pitch up, increasing the angle of attack on the wings, and causing what was originally an incipient stall to turn into a fully developed stall.
This is the theory. I've never tried it in practice as bogbeagle suggests, although I might give it a go. I don't know if bogbeagle has ever tried it?
