Not so, in fact a very bad explanation which I would interpret as stalling the aircraft above the ground. You are not destroying lift(thats done on the ground by decleration or devices such as air brakes or spoilers) you are in fact reducing the amount of lift to below that required to maintain level flight, thats what produces the descent which you call sink.
I dont see what is wrong with the use of the word destroying! Had I used the word destroyed lift then yes the aircraft would be in a stalled state.
I also question the assumption that lift can only be destroyed on the ground.
Take one accident where a student attempted to flare at 30 feet agl? The aircraft fully stalled and dropped a wing into the tarmac injuring the student.
I would say his lift had been destroyed in the air.
So I am quite happy with the word destroying when directed at ever increasing angle of attack.
