Do you mean brake torquing? Like what airplanes do at the end of the runway before rolling for take-off? Brake on while the engine is on full revs.
The things which I can see going wrong are, brake wear or engine wear (the groan or moan sound) from higher revs. Well, maybe not brake wear since the wheels are not turning (the pads might fall off though  ).
"Brake Torquing A procedure generally used in performance tests to improve the off-the-line acceleration of a car equipped with an automatic transmission. It is executed by firmly depressing the brake with the left foot, applying the throttle with the car in gear to increase engine rpm, then releasing the brakes. Brake torquing is particularly effective with turbo charged cars because it helps overcome turbo lag."
Unless yours is a turbo CSVT or ATX SVT  , you probably don't want to have anything to do with brake torquing.
