The 'Let Me Hear Your War Cry' meme originates from the iconic 1987 film 'Full Metal Jacket,' specifically the scene where Gunnery Sergeant Hartman confronts Private Joker during basic training. While the original cinematic scene is intense and intimidating, the internet has repurposed the dialogue to highlight the hilarious contrast between a demanding request for aggression and a hilariously weak or adorable response. It is frequently paired with images of small animals, such as the desert rain frog or tiny kittens, making a high-pitched 'squeak' instead of a roar. The meme serves as a versatile template for any situation where someone is trying their best to be intimidating but ultimately fails in a charming or pathetic way.
