It’s just terrifying.

A person in a black and grey camouflage outfit and a black balaclava stands in a narrow hallway, repeatedly lunging forward with their right arm extended toward a hand holding a pink and white polka-dotted paper cup, then pulling back, repeating the motion in a rhythmic, playful attack. The scene takes place indoors, in a hallway with light-colored walls and a cabinet visible to the left.
