Lenny is the gentle, vegetarian great white shark from DreamWorks' 2004 animated film Shark Tale, voiced by Jack Black. As the son of mob boss Don Lino, he struggles with his family's expectation that he be a fearsome predator, despite wanting no part in hunting other fish. His failed attempt at a menacing roar captures that conflict in a single moment. Online, the clip circulates as a reaction sound for bluffing, false bravado and harmless intimidation, because the character's soft nature undercuts the threat and makes the scene easy to reuse in memes and short edits.
