Sometimes I have heard the word "rolling" said by the pilot being cleared for takeoff; sometimes i've used it myself (what about you?).

My question: is it correct to say "rolling" to warn the controller that you are really starting the takeoff roll,in the case there was a delay between you starting the rolling after receiving the takeoff clearence, or is not necessary,and controllers depracate the use of it.
thanks B_D
