Broken heart, The light of my life, It's raining men, Stench of failure. "Like a Rolling Stone" Bob Dylan, "You Ain't Nothing but a Hound Dog" Elvis, "I'm a rocketman" from "Rocket Man" Elton John, "I really love your peaches, wanna shake your tree" From "The Joker" Steve Miller, "You shake my nerves and you rattle my brains" From "Great Balls of Fire" Jerry Lee Lewis. Threw some song metaphors just for fun.
A metaphor is a comparison that doesn't use like or as. For example: "The rocks that stuck out of the water were the teeth of a monstrous beast." "The melted sugar was molten lava." "The dancer was a delicate insect; her feet seemed to never touch the ground."
