What is "hot-rod"

Usage examples of "hot-rod".

The sun struck her across the face, and she closed her eyes, breathing in the scents as if they were memories: cars and chrome, miniskirts and oversized jewelry, hot-rodding in the Valley, hot groping in the back-seat, lipstick as bright as any neon sign, kohl as black and thick as pitch: desperate attempts to escape her sadness, her prison - Diana's Garden.
