To plunge the strongest arm forward at high speed and power penetrating through the chest of a person and/or zombie at full thrust in the shape of a Rhino charging. The result being an unrealistic head explosion upon pulling out and a bloody hand. Best used when wearing gloves.
Or inserting a fully erected penis into a womens vagina before foreplay.
One of Albert Weskers 'other' better finisher moves Rhino Charge which he used in the 'lost in nightmares' scenaio in Resident Evil 5 to kill Spencers guards.
